No sorry I don't remember what wire it was I used the wiring diagrams in the back of a Haynes manual. The oil pressure I bought a plate for the spot on the oil pan and plumbed in the factory oil pressure switch and the temp I bought the 3 prong switch from a 98 f body and the pigtail off the tbi tps sensor will work to splice in the 6.0 temp wires and the extra goes to your factory gauge. Although mine is off by about 20-30 degrees. Sorry didn't answer before now been away from home for a few days.
