96+ Passenger Firewall Bulkhead Connector

[Thunder5757]

Hello all,

Working on a 96 c1500 engine harness.

Did a lot of searching without much luck.

Need a wiring pinout for the passenger firewall bulkhead connection. Truck I'm working on was cut there.

Thanks in advance

Did you ever figure out what they are for? My purple and green wire are ripped idk how that happened

Old thread but I’d be interested in a list of these wires as well

There in the OE service manual. Wire diagrams, locations , some connectors also have part numbers. If, if you look you will find them.
