*****I have since undone this Mod and redid it from the Brake pedal harness,-much easier with better results*****




Please move to DIY!

I really wanted to do this mod and there has been interest from others but there were no pics with the original post, so I decided to give it a try. I will be doing a few mods over the next couple of days, and will do the pics and posts on some of them, some of what I'm doing has already been posted with pics.

Let me just say that my Paint shop (or whatever) skills are really non-existent.

Parts list: (all pepboys)

1-40' 18ga wire-$5.99
2-Black Wire Loom 3/8(could go smaller)x 5foot-$4.50x2=$9.00
1-Assorted small wire connectors(I had all) about-$4.00
1- Large Black switch(non lighted, very incognito)-$3.49

Here are Misery's original instructions:


disconnect and remove battery.
remove battery tray (4 bolts)
pull out bottom ECM plug
cut open harness and find red wire with white stripe.
mount any type on on/off switch in cab (where ever you want the switch)
run wires from switch through firewall and into engine bay(near fuse box)
cut the red/wht wire, and connect the ECM end of the red/wht wire to the acc. side of the switch and the other end of the red/wht wire to the supply side of the switch, tape 'em up and re-assemble everything in the reverse order, your done.

This mod took me nearly 2 hours with no pics to reference.

First remove both battery terminals, and unbolt the battery hold down bracket(Green arrow-pic 1). There is a sleeve on the battery casing, remove it , then push battery toward the engine, wiggle and lift up.


OK first pic is with the battery removed looking down at the battery tray. remove the 3 bolts with yellow arrows, and the clip w/ blue arrow. I removed the fuse panel w/ orange cover by unhooking clips w/ red arrow. You may not need to to this. The final tray bolt is hidden very well by wire loom w/ purple arrow. I removed this bolt with a long extension and swivel, then pulled the tray, then pulled straight up on attached panel.

Pic 2 is of the wire loom clip that has to be undone from the bottom of the tray so it fully removed.

Pic 3 is the 2 ECM wire harnesses. I found the easiest way to get to the bottom one is to remove the top one first, the the bottom(the one you really want). The clips are neat, just press the small tab and slide the "arm" all the way. Then GENTLY wiggle the harnesses out.

Pic 4 is the red and white wire described by Misery. Gently slice the electrical tape with a knife, and pull back the gray loom, to expose the wires. locate the wire and cut in the middle.

The hardest part was finding a place to pass through the fire wall without hurting something. I finally found A spot next to the steering knuckle. Pull back the sound deadener, and drill a hole about 2 inches over from the knuckle. Angle the drill towards the passenger side and go for it. Pic 5

I pulled the wires through the firewall and cut about 3 feet of loom and covered them under the dash. Next I removed the bottom dash cover(two screws underneath), picked where I wanted the switch, drilled my hole and installed switch. Then cut the wires to length, mine switch required male blade connectors, so I crimped them on and wired my switch. Pic 6

I've reached my photo limit, will continue next post.

Pic 1 is where I choose for the switch location. I then replace the panel and moved back to the engine bay.

Next I loomed the wire in the bay. I choose to run the wire above the AC evap line. It is a very clean run and don't need any wire ties, it sits snug in there all the way to the ECM. Pic 2 Highlighted yellow.

Next cut your wires to length, and Crimp the ends of the Ecm wires to the new wires, replace the gray loom, re-tape everything, and replace the harnesses, bottom first, then top. reinstall the tray and small fuse panel, battery, battery sleeve and hold down.

Take your time and you will have a very clean install.

Also did the fog light mod while I was in there

I haven't tested the results yet, I have more mods to do tomorrow, so my battery is still out. Pic 3

Hope this helps someone!!

Thanks for the nice write-up!

whatcha doing with all those other pieces parts? mystery modding?

I see the TB spacer.......

you must wanna race sometime soon! :)

Nice Write up, Didnt have any pics when i did my splice at the pcm so i was praying "please be the right wire, please" LOL. nice install i did mine the same way you went next to the column. GJ. Now go test it out and buy some tires right after.

Thanks! What sucks is I don't even know if I did it right, cuz I can't test it yet.

Hey Chicks, more posts coming. TB spacer will be a write up since its the $38 dollar knockoff. Coolant bypass won't be, and some AEM "alterations" will be and MAYBE??? a cold air pick up(not sure about the feed hose yet).

haha, so you made this write-up and it could be wrong?!? lol uh-oh.
You should put a disclaimer.

Thanks for posting this...I have been entertaining this Mod.

LOL!!! Knowing my luck!!
But seriously, I followed directions exactly, and others have done it. I did state somewhere in there that I have not tested it.

gr8 job I can't wait to do mine!

Please move to DIY!

Done.

Thanks

isn't there a way to do this at the brake pedal? I think it was the lower harness next to the brake pedal but I don't remember which color of wire it was. there are 2 wires and i don't want to be wrong. I'd prefer not to have to go through the firewall if at all possible. not that it's a biggie, but odds are a dealer will never see mine, given that my remote star kill is in the exact same place. I'd be sneakier for my application.

on the brake pedal mount there are 2 switches, I believe one is black and one is brown. there was a diy about which you could remove from it's "holder" and therefore have done the burn out mod without cutting any wires. I'll look around and see if I can find it.

no, no, I know you can unplug it, but if you can unplug it and make it work, you should be able to run a switch to that plug and not have to deal with unplugging it.

I jsut can't find the old thread. it was the lower plug and the red/orange wire on it i belive. don't quote me on that.

Looks like you found the heat wrap you were looking for...

What might the future hold??!

the heat wrap mod, and the TB spacer are done, writing post in about 10 mins.

I tested today, but unfortunetly my nitto are just too heavy and aggressive for burnouts. but the ECM did't shut me down. The tires would spin for a couple of secs, then stop, then spin, like the tranny was building up pressure or something. I was probably braking too hard. Only one wheel - the passenger side.

Great write up! I decided to do this off of the harness at the brake pedal. it is the red/green wire on the lower harness if you have the console shifter, NOT the column shifter. Just clip it and install a switch, and away you go. I didn't want to have to run through the firewall. Just thought I'd post this as an alternative.

By the way, I could always break loose the peg leg burnout, and thought it wasn't THAT lacking in power... but let me just say, the combo of this and the Banks, or really any aftermarket exhaust i'm sure, and the effect is STUNNING. LOL. you would think a prostock car should come out of the smoke this truck now makes. LOL... time for a new tire.
:thumbsup-big:

Thanks for the alternative KingBean, I wish I had known it sooner, I would have done it the easy way!

Only one thing - when done at the ECU, does it disable your taillights and neutral safety switch? when done at the pedal, it disables your brake lights, so be SURE to turn it back on.

Great write-up!!

From the ecu it doesn't disable the brake lights. I had brake lights in both switch positions.

Cool writeup. I'm going to keep checking out the board.

I put my switch....here...

so whats this actually do? let it spin 1 or 2 tires haha? i read about this and im like? i can get my cc to spin 2 sometimes if i get the pedals right. Other then that just one tire frier:(

does this protect like the brake pedal mode one,cause if u do it on the brake pedal if the switch is off it will not let u shift to any gear even if u press on the brake pedal?will doing it on the ecm side do the same?
