Relay:

Relay is just like the one in post #219

Pin #86 to ground (blk/yellow 16 or 19 AWG)
Pin #30 to battery w/ 10amp fuse (red 10 or 12 AWG)
Pin #87 to 02 sensor (purp/blk 10 or 12 AWG)
Pin #85 To ingtion hot (brown 16 or 18 AWG)

Also, I do have an aftermarket VSS. The instructions said to ground the vss to the computer. Do I need to do this or ground it to the tranny/t-case/frame?

Thanks again for all the help and answering my amature questions

If I am lucky, it will be running next weekend.

If you run pin #85 on the relay to an output pin on the fuel pump relay it will keep you from overheating the oxygen sensor when the ignition is on but the engine is not running (like when checking codes). The heater will then be turned off when the pump is powered down by the ECM.
