Using a 00 PCM/Harness in a 98 V6 Car??
Using a 00 PCM/Harness in a 98 V6 Car?? Hey Guys,
Ok from what i read to run a LS1 in a 98 V6 using 98 PCm/Harness its pretty much plug and play.
NOW...since I already have a 00 LS1 and harness/pcm and I am swapping this into a 98 V6 car,can I do so by just changing the pinouts that go from the PCM to the rest of the car?
Or is it easier to trade my 00 Hanress and PCM for a 98 unit??
Also,should I use the plastic fuel tank,etc from my 00 Z28?or just keep the steel one and not worry about running new fuel lines etc (due to v6 having 2 instead of 1)

I believe the 99+ dash harness is different because the pcm talks to the gauge cluster differently. So you may have to get the dash harness too.
I used all 98 parts (harness, tank, cluster) in my v6->v8 swap. To avoid having to rework the tank and fuel lines (plus I wanted a return style setup anyway) I used a '97 vette fuel rail and fpr. If you go with the '00 pcm, you'll have to deal with the fuel gauge difference too (compared to the 98 sender and gauge).
The simplest/cheapest thing to do is probably move everything over from your 00 to your 98. Then you won't have a mix of parts on the car.
You could re-pin the harness to match the 98, but there are a LOT of wires that are different. You'll also have to have the 98 pcm. If you have a 00 parts car, my advise is to plan to swap EVERYTHING to the 98.
Around 176 of the 180 pins/wires on the pcm are different.
No need for the newer dash harness- delete/ swap 17 of the 35 pins there.
Use EFI Live and your fuel gage will work with the 02 Express Van fuel segement.
Take your pick with the fuel lines- stay with the 98 V6 return style and get a 97 Vette fuel rail OR stick with your 00 rail and delete the return line.
Sell / donate the 98 pcm to the Smithsonian.

To clarify on the fueling, if you go '00, you need the tank/bucket/integrated regulator from the '00 too.
i did this swap in my 00.. first off you want to go newer than 98. and you should get a gauge cluster although i dont know if you have to cuz i put mine in before i did the swap and it worked fine actually.. one thing you will need to do is wire in your injectors (had a friend help with this one)
and about the fuel line situation you need to just go with the v8 style fuel lines. i had way to much fuel pressure keeping the v6 style and get an ls1 gas tank and sending unit all of it..

The '97 'vette rail (and fuel pressure regulator) is what solves the fuel pressure issue. That lets you keep a rail mounted fpr like the v6 had. If you run a f-body 98+ ls1 rail, it has no fpr, so you end up with whatever max pressure the fuel pump can develop. But if the '00 donor car is sitting there, it's probably easier in the long run to just swap all that fueling stuff over, from tank to rail.

Verdad Gallardo Wow I got replies..Thanks Guys,
I kinda gave up on it,lol (the thread)
But I was goin to use my 00 fuel tank and the V6 feed line and put a T on it and route it back into the tank for the FPR..will that work?
Also..will I need to re-pin the fuel pump harness that plugs into the body?
And as far as the 98 car having 3 plugs in the firewall..how do I re-pin it down to 2 plugs like my 00 harness has?
And lastly..The whole INJ2 power supplu..do I just put a power wire to it,use a fuse then where do I run that wire to give the bank power?
Also I planned on running a 99+ Gauge cluster anyways so thats fine,but I guess I'll need to re-pin that plug for that too?
Anyone have a diagram on this?
Joe

I found one of the rear o2 heater wires in the bundle on the fender, and ran a short jumper wire from it to the INJ2 wire in the same bundle. (this was on the PCM side of the connectors) That way I knew the wire would be hot at the right times and would be fused. And I wasn't using the rear o2 heaters anyway...
This is the only one of those questions I can chime in about.

Mine was a 98 pcm so the wiring is probably different.
If you can track down the wiring pinouts for the 3 (2?) fenderwell connectors, identify the INJ2 wire, and a rear o2 heater wire. Then put a small jumper wire between them. Or just cut each one and cross-connect them. Your chassis harness will be feeding switched/fused 12v to the rear o2 heater wire, and tieing it to the INJ2 wire will then feed that circuit.

You need to feed C101 B.
If you don't have EGR you could use C100 G.
