Ok I swapped a speed density 350 into my 1992 camaro which came with a 305 TBI. I am using the factory camaro dash harness and a 1990 Pontiac speed density engine harness.

The problem is that the big connector that plugs into the driver side firewall that goes to the fuse box and guages have the pins in different locations, and my guages aren't working correctly.

Could somebody help me out with some wire diagrams for a 1990 pontiac and a 1992 camaro, so I can figure out how to re-pin these.

 

Here is the instrument cluster pin-out for the 92 camaro and you already have the C100 connector pin out. It is the standard pin-out on all the 92 engines.
