help needed with guages wiring ..
thanks for looking
these 2 guages will go in my Alfa (thanks Matt
) ... mine did not have them (a 4-door '82 series 3) but they will slot in nicely in the centre console.
obviously mine is not wired to take them (i still have to find out if there is a sender unit on the engine block for the oil pressure guage) but i'd like to get them working although i DO have another engine temp guage on dash (why is that ? did the Ti's have something else there?)
4 wires come out from each .... yellow / white / black / blue ... quite clear that yellow are the bulbs and black is the earth but why do i have another 2 ? the sender unit only has one connector. and any idea how to go about wiring them ? and even though i know yellow is to light the bulbs do i just connect it to another wire going say to heater control illumination ?
thanks, pics below.
