scotty Posted September 16, 2006 Report Share Posted September 16, 2006 I need an idea of where to punck a new hole to allow haltech wiring to come onthrough to the other side. I do NOT plan on removing the dash to make this happen . Link to comment Share on other sites More sharing options...
ZPI28 Posted September 16, 2006 Report Share Posted September 16, 2006 Scotty I removed the glove box and ac fan. This allows you access to the firewall, you can pull the wires through the hole right by the ABS canister. Its not that bad if you remove the passenger seat and the ac fan.

SHhhhh Posted September 16, 2006 Report Share Posted September 16, 2006 Scotty I removed the glove box and ac fan. This allows you access to the firewall, you can pull the wires through the hole right by the ABS canister. Its not that bad if you remove the passenger seat and the ac fan. Steven This is what I did and was the easiest way. Just follow your factory O2 sensor wire to the firewall and you will find a spot there. Use a razor blade to get through the insulation material and rubber piece, and just enlarge that area. This hole is big enough to get that harness through there. Then you can mount the Haltech computer in the glove box for easy access. Link to comment Share on other sites More sharing options...
88TSI_Rob Posted September 16, 2006 Report Share Posted September 16, 2006 It can be done without removing the AC fan as well. I taped all the wires to an outstretched metal coat hanger. There was enough room to feed the wires through even with the stock ECU wiring in place. Link to comment Share on other sites More sharing options...
button Posted September 16, 2006 Report Share Posted September 16, 2006 i ran mine through the stock location.longer wires, but cleaner IMHO. Link to comment Share on other sites More sharing options...

Boosted_One Posted September 17, 2006 Report Share Posted September 17, 2006 Scotty - are you keeping the AC? I went thru the passenger side AC area where the condensor was. Nice big hole there. Seeing the ECU is in the glovebox it worked out perfect for me. Link to comment Share on other sites More sharing options...
Richie_Rich Posted September 17, 2006 Report Share Posted September 17, 2006 You can go right through where the speedo and cruise cable goes.It's awful close to the engine heat though. I ran my Profec wires on the passenger side.Pain to grab them inside the car though.I did have to drop the A/C box and fish a coat hanger through.

Chad Posted September 17, 2006 Report Share Posted September 17, 2006 here are some pics, I'd post all of them, but it's too much bandwidth. If anyone wlse want's to host them, feel free. http://webpages.charter.net/catsamuel/DCP00963.JPG http://webpages.charter.net/catsamuel/DCP00964.JPG http://webpages.charter.net/catsamuel/DCP00965.JPG http://webpages.charter.net/catsamuel/DCP00966.JPG http://webpages.charter.net/catsamuel/DCP00967.JPG http://webpages.charter.net/catsamuel/DCP00968.JPG http://webpages.charter.net/catsamuel/DCP00969.JPG http://webpages.charter.net/catsamuel/DCP00970.JPG http://webpages.charter.net/catsamuel/DCP00971.JPG the best way to locate that hole so it clears everythign is to drill several 1/8" holes till you find the desired center of your hole location, it's nearly impossble to locate the hole without doing this, you'll end up with it offset too far one way or another. When you find your hole center, you can then open it up with a hole saw, using this 1/8" hole for a pilot. I used an 1-1/4" (trade size) electrical fitting, it's $2 and easy to find. After you run your wires thoug it, you can seal off any gaps with silicone or RTV. If you want to run stuff thoug in in the future, it's not to hard to take it back apart. To use the 1-1/4" size, you need a 1-5/8" hole saw. in the pics you can see I was able to pass an SDS harness though it by taking appart the DB-25 connector. I've done a few cars this way, it is easly done in ~1 hour, and if you ever changed your mind, you can get a 1-1/4 "KO seal" (trade name for a 1-1/4 counduit hole plug) and cover the hole with a nice/cheap/rigid metal cover.

scotty Posted September 17, 2006 Author Report Share Posted September 17, 2006 I may leave the bulk of th factory ecu harness connected so i can use the factory oil pressure guage and the a/c etc without tracing the wires and probably having to remove the dash to get to that stuff . Im lazy Where is that fabric loom stuff available for wrapping the harness ? Link to comment Share on other sites More sharing options...
Chad Posted September 17, 2006 Report Share Posted September 17, 2006 www.mcmaster.com I forget what it's called on their site, took me a while to find it. It's categorized with wire shething and wire/cable protectors. Link to comment Share on other sites More sharing options...
Chad Posted September 17, 2006 Report Share Posted September 17, 2006 Found it, search for item # 9284K411, when you get the page loaded, click on "catalog page" and you will find all the different sizes and colors. It needst to be finnished off with heat shirnk or it wll unravel at the cut ends. Link to comment Share on other sites More sharing options...
Richie_Rich Posted September 17, 2006 Report Share Posted September 17, 2006 I was just going to post it was around page 735. Thanks for the part number.That stuff looks real professional. Link to comment Share on other sites More sharing options...
Chad Posted September 17, 2006 Report Share Posted September 17, 2006 Further down that page they have tined copper mesh too, looks like braided stainless when you are done 8) I made an entire harness with that stuff, looks bad-tail. It does corrode eventuly though, looses it's luster if you live in a marine environment like I do. It still holeds up well though. Link to comment Share on other sites More sharing options...
