Anyone have these things?

What do you guys do for your swaps???

Allot of guys buy the helms manuals. I have 98 so I can't help you. You have an e-mail to a link with the info you are looking for <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" />

I'm swapping in a 99 LS1 into a 97 V6 firebird.. I have my harness pretty mapped out but to do so I had to pretty much disassemble my V6 harness and trace wires for hours.

Does anybody have the pinout diagrams for the locations where the PCM harness plugs into the dash harness and the underhood harnesses?

I also could use fuel pump wiring diagrams. I'm re-using my 97 fuel pump wires... which are 3.. but the 99+ ls1 setup requires 4 wires.. I'm hoping 2 of those wires are just grounds.

Thanks!

I have the PCM pinouts, I just need the pinouts where the harnesses meet.

I'll try to find somebody local with a helms manual. Maybe someone has one on here?

I have a 99 helms. At the pump it Looks like this.

1. Grey wire 120 Fuel pump
2. Black wire 150 Fuel Pump Ground
3. Blk/Wht Wire 651 Fuel Level Sender
4. PPl Wire 30 Fuel Level Sender + 5

If you need it I can take a picture of it and post is on my ftp site.

Thanks Dale!!!

Once I get all the wires to match up, I'm good to go!

I still don't know how the starter is triggered. I see the purple relay wire but was unable to trace it.

This thread is really old, I know, but the link above doesn't work and it's all I could find.

Does anyone have the 99-02 underhood harness pinouts?

Are you needing the pinouts for the engine harness?

No, I'm planning on putting a 99-02 steering column and dash in my conversion and was hoping to use not only the engine harness but also the underhood harness and interior harness. I have the engine harness pinouts, and was hoping to get the pinouts for the others.

Is there such a thing, or am I confused? (thanks for the schematics by the way)

You may have to sign up for AllDataDIY. You can get every schematic for the car you're working on and I think it's about $25 for the first car.

check out my post, i think you're working on the same? I'll post up the schematics from the GM manual later tonight. I have one of those GM bootleg CD's which was very informative and cheap.
