I'm working on adapting the P-body smec harness to my L-body, and have some questions. The diagrams I found were only for half of the connectors on the harness...the other connectors that are downstream from the firewall gromet aren't there. I'm going to try to figure it out with colors and sizes and all of the other diagrams I have, but I have something that I'm trying to figure out first.
There are 2 main branches of plugs on the P-body harness, engine to instrument panel, and then 4 other plugs. Some of the wires on both of these go through the firewall gromet to the engine harness, but some of them go to the other connectors inside the car (I have pictures of this...I just need to get them off the camera). What I'm wondering is this: Do I need any of the wires that send signals between the two branches of plugs? It seems like these are just part of the interior wiring on the P-body, and my L-body interior wiring will deal with all of this after I get it wired in. Do I only need to worry about adapting the wires that go through the firewall plug to the 40 pin bulkhead connector?
Sorry if this is confusing...I'll try to post pictures later of what I'm talking about.
