Wiring the 3 hole Gauge Cluster

[myoldchevytruck]

I emailed GMC Paul to ask for his expertise but I know things have been hectic in his neck of the woods so I was hoping there was a board member who was wiring saavy. A fellow board member referred my to GMC Paul's tips link for the cluster connector but I am still a bit confused.

I am re-wiring my 1969 SWB and I am using an after market harness (Rebel Wiring). So far, everything is going smooth. I am using a 3 hole bezel in my truck (I seen the difference between the two - same plug, different setup).

I have matched/used the following wires on the connector: #7 Pink, #9 Green, #10 Light Blue, #11 Dark Blue

I have the following wires left in my harness: oil pressure, water temp, tach (I am using an after market gauge pod)

AND A RED WIRE LABELED: GAUGE POWER

Other than the gauge wires in the connector, am I using anything else? How about the #6 black wire/ground on the connector - do I run that to a body bolt for ground?

Sorry don't know the answer but here's a bump for you.

water temp wire will be re-used if your using and electric gauge
oil pressure wire will be deleted unless your using an electric pres. gauge
i don't know about the tack wire..
i had to add 2 wires to my idiot light harness with 4 amp fuse each, 1. to term. block by battery(gauge power i guess)
2.to red wire on back of alternator.( for amp gauge)
if you still need some help you can call or e-mail paul @ gmcpauls and he will help you.

lilred, I emailed him earlier and I think I'm straight now. I have to do the H/L switch, that'll give me light to the gauge bezel.

Thanks
