no dash lights

could not find power out from the barrel connector..

What do you have for a wiring diagram? The barrel connector won't have power except to certain pins under certain conditions

I understand this is a 68 valiant?

below is where things go on the connector



On the picture above, A, dk blue, will be hot only in "ignition run" and maybe "accessory."

B, "gas gauge" will show continuity to ground and is the sender wire to the tank. No power when disconnected

C, "temp ind" same as above except goes to temp sender

D "instrument lights" should have power when light switch is on

E "high beam" will only have power with lights on in high beam

F L direction obviously will blink as turn signal on Left

G same as above, right

K Same as temp and gas, temp--goes to oil pressure gauge sender OR to oil pressure light switch.

L brake warning light will only have power if the brake warning switch is activated.

Ammeter must be hooked up, (or wires jumpered) and cluster must be grounded.
