Re: 91 Suburban Issues
The mystery relay is the fuel pump relay. The wire colors are the same as the earlier TPS; I'll be finding out pretty quickly if is is a direct swap. I am putting a 91 engine in a 87 truck. I don't know if there is a seperate ESC module; it may be in the computer. You may also want to check your wiring to the knock sensor also.
