Guys, i need your help. I want to order a PSI harness for the Chevelle but im confused which one to order.

You have the P/N HAR-1084 harness which says it has the "2 CONNECTOR THROTTLE BODY"

http://secure.ultracart.com/catalog/.../HAR-1084.html

or the P/N HAR-1014 which uses the "SINGLE (8 PIN) CONNECTOR THROTTLE BODY"

http://secure.ultracart.com/catalog/.../HAR-1014.html

Im using the Nick Williams 102mm DBW TB.

Next is the options:

Im using the original LQ4 injectors, part# 25320288 so which one to choose from: Multech? EV1? EV6?
Oil pressure wiring: Yes? No?
AC: Yes
Coolant temp wiring: Yes? No?
Fuel level wiring: Yes? No?


And now the PCM

http://secure.ultracart.com/catalog/.../PCM-1003.html

Model? The engine is from a 2000 chevrolet silverado 2500 2WD with LQ4/4L80E
Intake? I got a Holley hi ram LS3/L92 ports
Fuel injector type: Im using the original LQ4 injectors, part# 25320288 so vortec truck?

The Monte pedal only works with GenIV engines and ECUs. Looks like you have a Gen III and will need a TAC.

After 3 long and painful years, i finally have fenders and a hood on




Door gaps being checked





Floor pans had to be primered again for paint


Unfortunately, the regular hood wouldn't close with the Holley Hi-ram and tall and narrow mounts so i switched to the short and wide ones in the hope it will bring the engine down more but it was a no go.

Trimmed the X-brace on the underside of the bonnet but still didn't help so it either i get a Mid-ram or 2 inch cowl hood like toytech93 did. Im going to go with the Mid-ram and switch over the openings in order to retain the 102mm opening and the NW TB but i got the engine to run, ill try to upload a clip of that
