im not sure where this wire goes that i have coming off the engine harness on my 87TII, the wire is yellow right a red strip and comes off over by the oil filer neck. it doesnt have a connector on it cuz it broke off buti dont know where it goes. also what color wire goes to the thermo neck for the gauge. last bu not least i think i might have a NA pressure sensor, because my friend pointed it out and when i try to boost the car just stumbles and starts spitting but it ill cruise finebut whont hold idle.

the yellow wire is probably either the oil press sender or the temp sender. I would have to consult the FSM for the wire color. You missing any of those readings?

THats your temp sender for the gauge. The one on the water neck is for the ECU only.
