98 LS1 + T56 swap in my 79 Monte. Wiring harness? Which one?

[CruizinKev]

Hey guys,

at the moment I'm planning parts lists and so.

I'll get a 1998 LS1 with stock PCM and a T56 for my Monte Carlo 79.

Which wiring harness I should get? I'm a noob when it comes into these things and I don't know much about stuff like that.
I looked on ebay and found this:

What do you think about that? This will work with my project?

I'm reading about VATS delete and stuff. I asked that ebay seller about that and he said his wiring harness will not work with the 98 PCM because their harness build for a 99 PCM which is different.. IDK about that. He's offering the right PCM with VATS and emissions delete, lowering of fan temperatures and updates for the correct tire size and gear ratio for $185. So total would be $614 for wiring harness and tuned PCM.

Like said I don't know about stuff like that. I'm looking for a kind of "plug and play" :1st:
What do you think about that? Got any other ideas/links/shops?

Sounds like a good price to me. The harness seems to be made with good quality components. The fact that the PCM will have un-used functions deleted is a bonus and time saver.

I used a Painless # 60507 harness. This is the extended length version (about 6ft. IIRC) and allows PCM to be mounted under back seat or wherever.
It REQUIRES a 1998 pcm, so would allow you to keep yours. you would still need to have emissions etc. deleted to keep check engine light off.

I was in the exact opposite position you are in as I have a 99 motor, and had to buy a 98 PCM.

Before you buy the '98 harness you may want to look into selling the '98 PCM and getting a 99+ as most tuners would prefer the newer PCM.
