does anyone have the wiring diagrams for the PCM Pin outs for the riviera and or regal supercharged 99+

Im pretty sure my motor is a 99 of one of the two but Im not certain and it seems like the PCM pins are completely different then the GTP so any help locating the PCM pin outs for those buicks would be very helpful Im in the last steps of my harness and just need to figure out what some loose firewall wires from the old buick harness are to see if i just need to eliminate them or if they are something I need to use.

Should have all you need on GMtuners site.

Not that quick... I have always done them in little to no time at all. After you clean off the harnesses, you just need to connect about 25 wires... it does NOT take long at all.

DarkHorizons right its not as bad as people make it out to be, it can be time consuming but if you go at it with a game plan its actually quite simple this is my first swap and its been a breeze more or less, had a harder time getting a gtp supercharger tensioner then anything else involved. Engine was out and the 3800 was in physically in less then a day. I expected it to take more effort. Wiring is done pretty much just gonna double check over things get all its fluids and then all thats left is to find out the length of my alternator belt and buy one (my pulley setup its pretty unconventional)

I forgot to add that I did a loom off harness too so its pretty clean to boot :P
