Which fuse gives a 5v feed from fuse box?

Hi guys, save me ploughing through the factory manual, can anyone tell me which of the fuses in the box provides a 5v feed (if any) as I want to send power to aftermarket temp guage, thanks.

no fuse provides 5v ....that is done by the instrument cluster voltage regulator on back of dash.

You cannot send 5v to aftermarket gauge, all of those will run on 12v

Really? Ok I have a problem, maybe. I fitted an aftermarket temp,guage. Powered it with switched 12v and used the original mopar sender unit and wired that direct to the S terminal one the temp guage.
Guage goes up to full hot (120) within minutes of running the motor. I cannot believe that this is accurate especially as I have just fitted a new aluminium radiator.
Have I missed something?

I'd go with a mechanical temp gauge, way more accurate.

yea...you cannot use after market gauge with OE sender...where's the sender for your gauge you are installing?

I would go with mechanical bulb style as well, the electric gauges suck..those are never accurate

Ok guys thanks for the heads up. I bought the guage off a guy, no sender and when I asked for it I got no reply.
Time for mechanical, works good for oil pressure!
