94 caprice LQ4 swap

Need some guidance.

So the factory underhood wiring harness needs to be stripped of all the old LT1 stuff. (I'm running an ebay standalone).

So on the factory harness I'm keeping the Power Steering, AC line, Compressor, coolant bottle, trans line, underhood light, and grounds.

Am I missing anything? I don't want to chop something I need.

Go here for the info you need. If you identify each wire in the bulkhead connector that goes through the firewall and out of the bottom of the fuse panel it will answer the majority of your questions.

I just started pealing off the LT1 pcm pins that went to the fuse/relay panel and kept the wiper and washer pump wires as well as the abs wires. Fuel pump oil sensor and alternator wires need retained. Everything else can be eliminated but verify with the main connectors
