Harness colors don't match any diagrams???

What exactly are you trying to do, test them?
If you are trying to test your tps, you can do it without a diagram. There should be 3 wires. Your Signal, 5v reference and ground. Take a multimeter from B- at idle to all 3 wires on volts. The 5v is your reference, the one that is between .9 and 1.2 is your signal and the other is your ground. For your ect, just check resistance of the sensor itself, check it at operating temp, and again when cold. Compare Reading's to alldata or one of jricter's link. Sorry, I can't remember the ect or tps wiring. I think the middle one is your sensor wire though. If you don't have a scope, do a slow sweep of your tb should go from around .9 closed throttle to about 4.6 wot. ---I think.
If this doesn't help your cause, sorry. I don't remember colors.

Take your pick of the diagrams...
