I would like to get the original temp and oil pressure gauges hooked up in my cuda. Problem is I don't have the connectors for the ends of the wires to connect to the pole on the sending units. They are the rubber covered 90deg ends that slide down onto the pole on the senders. Does anyone know where I can get these without buying a completely new harness?

Try M & H at the above web site.

I have a box of wireharness just for clipping ends and splice out of them.

you want a stud push on 90* end that is most times orange color wire(what my truck always have)

and the same stud push on 90* end for a oil sender that most times is a white wire.

oil sender also use a stud with flat tip and slide on spade connector with white wire also.

double check this one...?

I have both if IIRC.

Yes you are right...the oil pressure sender has a round flat top that a spade connector slides onto. What did this factory connector look like? Any different than a normal spade connector?
