720 4x4 gauges in my 521


Recommended Posts

Here is a picture of the harness.






Daymn , them pics I took blow goats.



Im pretty sure that r/y stripe and r/b stripe are light related. I have the gauges and the first part of the harness. What do I need to hook up all of them to? I know the two light ones need to go to the lights, and one needs to come from the 4x4 sender and hook to one of them. And y/r stripe is voltage? Just tap any line? Black ground? I searched and everything seemed to tell me to find the provision on the 720 harness. Wont help me here. Probally a easy fix but dont want to mess em up. thanks for any help.

Not sure what that is


This is a 720 oil pressure gauge wiring. (the volt meter only has 4 wires.




Red/Blue stripe........ to dash lights*

Yellow/Blue stripe..... to the gauge terminal of the oil pressure sender. (the other, Yellow/Green still goes to the red dash light)

Black........................ to ground




Yellow/Red stripe..... to #4 fuse or any ignition switched 12v supply

Red/Yellow stripe..... to other side of the dash lights*


* or just wire them 12v on one side and ground on the other from a switched supply. They will be on any time the ignition is but so what?

Are you talking about the console gauges?

Did you get the oil pressure sensor off the block when you got/bought the gauges?

I did all of this on my 521, I had to basicly put new wires everywhere and grabbed the power for the gauges/lights from a wire that was hot when the key was on like datzenmike suggested.




This is the sensor needed to run the oil pressure gauge/light, it has the wires coming out of the rubber cover.
