Two things that come to mind is the painless harness doesn't support the factory amp gauge, it's set up to support a volt gauge, and does it have a tach hookup? That would account for the two wires. This may help.

The information I directed you to is for rewiring a light cluster to a gauge cluster. The following may make it clearer. Connections 3 and 4 are for the amp gauge the painless harness does not support the factory amp gauge. 1 and 12 have two wires you only need one.

1- Light blue - Left turn signal indication light.
2- Gray - Dash lights.
3- Black/white. For amp gauge
4- Black. For amp gauge
5- Light green - High beam indicating light.
6- Dark blue - Oil pressure indicating light. (from oil pressure switch)
7- Pink - Power to indicating lights and gauges.
8- Tan - Brake warning light. (from park brake switch and brake distribution block switch)
9- Brown - Tach signal. (from coil -)
10- Temp Gauge. (from temp sender)
11- Tan - Fuel gauge. (from tank sender)
12- Dark blue - Right signal indicating light.

Thanks again Elree, things are getting clearer. I do have a few more questions Though.2 of the wires going to the dash block, from Painless, are a generator light wire,volt meter wire. Im I not using those 2 wires at all? I also see my Tachometer wire comming from the tach side of my HEI but not going to my dash harness. Do I run that wire (tach) to the dash block using the dash clips? I also need to know how to hook up the amp gauge. I have 1 wire high output Alternator.

"2 of the wires going to the dash block, from Painless, are a generator light wire,volt meter wire. Im I not using those 2 wires at all?"

You can have the amp gauge converted to a volt gauge, e-mail for info, you will then use the volt gauge wire, otherwise you will not use either of the two wires.

"I also see my Tachometer wire comming from the tach side of my HEI but not going to my dash harness. Do I run that wire (tach) to the dash block using the dash clips?"

That wire will connect to #9 - tach signal.

"also need to know how to hook up the amp gauge."

I'm not familiar enough with the painless harness to make a recommendation for connection locations. I just know that the harness is not designed to accommodate the factory amp gauge.
