We dropped the '01 305 Vortec in the CJ7. More's mounts are sick. Slipped in like a bannana in a $2 whore. Now we need fire. My bro looked for Howell. Did they die and fold up? No help there. Called Painful... I mean Painless. They quoted 5 hundo! AND he had to send the comp in to bypass the theft deterrent system AND, on top of all that, they dont even make one yet! Wont be avail for the Vortec till NEXT YEAR! WTF?

I KNOW some you doods are runn'n Vortecs. Where's the wires? thankyouthankyouthankyou!

I'm about to start a Vortec ('97 5.7L 4L60E) swap into a Toyota. From what I've heard, it is either spend $400-600 or spend MANY hours going through the harness yourself, and you still have to have someone reprogram the ECM. Check out http://www.fuelinjection.com I've seen their work and talked to them on the phone. You can send them your old harness and they send it back with about 6 wires that need to hooked up to your original wiring to make the thing run. All the factory connectors are labeled and cleaned/checked. They take out all the unneeded connections like ABS, etc. For my '97, they wanted $425 for the harness work (not including the ECM mods). The ECM mods were about $300 (?) including what had to be done to make it run without throwing codes and preformance tweaks.

Howel can be found at http://www.howell-efi.com/index.html For my application they started at $600 for the harness.

Any others ideas?

I went with the Howell harness on my '97 4.3. It works great, easy to hook up and simple. It was like $612 shipped to my door. Its a lot of money, but I think its worth it to know that it all gonna work right.

Try a place called Street and Performance they might be able to help.http://www.streetandperformance.com/
Hope that helps.

Check out this site....

Its a site for Camaros & Firebirds...
They have alot of tech boards, and folks that program chips etc..

There are board members that program chips cheap....

Jeff,
Call Zack at SpeedScene Wiring and he will set you up. He did both Adam and I's harness and computer reprogramming, Including a custom sensor for the Atlas. :beer:

Zack at Speed Scene did my Vortec harness. All wires were very well marked and the connectors were right on. However he was slow to deliver and the price is pretty high.

Aloha!

YOu doods rock. Thanks a bunch for the help. I used Howell for my TBI and spent about 300 out the door. Damn, guess multi port means multi dollars. :D

We're checking out all leads! Thanks again!!!

Use the OEM harness as long as it is complete. I don't understand all you folks spending big bucks on aftermarket harnesses. I have installed three Vortec engines now (the first over 5 years ago) in Cruisers and all have worked great with the OEM harnesses. Cut and seal off the wires you don't need, have the VCM reprogrammed if necessary and use the saved $$ on other parts.

I believe the point is to avoid having to spend the time going through the repair manuals figuring out which wires one does need. I have to say that I'm going to have a shot at doing it myself to save the $$$ Any hints for the DIY'ers?

Any hints ... Yes, buy the shop manual !!! Make sure you spend the ~$100 for the GM manuals. This is money WELL spent. Other than that, just start going through the wires. This is how I learned on TBI's, TPI's, and LT1's. Soon to be LS1's :)

Ditto! The shop manual has all the info needed. Just gotta spend some time on the floor with the manual and the wiring harness. I have only done one, so far, and looking back on it, it was actually pretty stressful at the time. You're not sure that you can actually make it run right. But my idea was, what did I have to lose, other than $79 for the manuals, and a few hours of my time(okay, so maybe it was more than just a few).

I used the factory harness on my TBI swap, although there a tons more wires on the Vortec ones. Once you have done one and figured it out, the second one is a piece of cake. The other benefit is that after using the factory harness, you have a much better understanding on how the system works, particularly if you have to trouble shoot a problem.

As for the factory manuals, IMO they are something you should buy no matter what harness you use.

I would also recommend a cheap scanner, I went several years without one, and wish I'd just bought one to start with.

IMO, this is the primary reason for using the OEM harness and doing it yourself. It forces you to learn the engine, electronics and how it all works. As one example, a few months after installing my first 5.7 Vortec, one day when I turned off the ignition the fuel pump kept on running. Had I not been forced to learn the wiring curcuit for the pump I probably would never have figured out that the problem was a faulty oil pressure sensor. Of course if you are lazy and not interested in understanding your engine, go ahead and give into the "plug and play" mentality:rolleyes:
