Guest Posted February 24, 2002 Share Posted February 24, 2002 Information on the wiring diagram for swithing from a light -gen,oil,temp,brake and big gas guage to a rally pack. Do yoyu have to change oil & temp sending units on the motor? Thanks Bob Reed Link to comment Share on other sites More sharing options...
66400 Posted February 24, 2002 Share Posted February 24, 2002 The sending units are different, the oil pressure unit also has a pipe tube and elbow which elevates it from the engine block level due to clearance. Oil pressure unit is much larger in diameter than the warning light unit. Sending units can be found in local parts stores, the fittings are sold by some of the Oldsmobile parts supliers.

rocketraider Posted February 26, 2002 Share Posted February 26, 2002 Couple other things to consider. You'll have to move some wires around in the instrument pod plugs, idjit lights and rallye pac use different locations, so you'll need a wiring diagram. Also- on 73-76, Rallye Pac cars had a separate seat belt warning lamp in a little nacelle that sat on top of the dash. And that thing is damn near impossible to get loose without destroying it.<P>From experience, I like GM sending units. Seems like aftermarket oil senders especially make the gage do weird stuff sometimes, fluttering, dropping to 0 and then back up, etc. Even respected name brands will do this.
