i switched out my 307 for a 454 and put in a hei distributor. on the 307 i had points and the wire going to coil + side has two wires my question is do i use both of these wires to my new hei distrubutor or just one and if just one what wire do i use there is a orange and yellow wire any help would be appreciated :beers:

The orange wire(usually in a sheathing) comes from the firewall bulkhead (check to be sure)and is a resistor wire. This wire needs to be changed (from the firewall bulkhead) so it can be used for the HEI.

The yellow wire comes from the starter "R" terminal (check to be sure). It was used to send full power to the points when cranking the engine.

You need to test the orange wire by itself (that you replaced) to see if it has power with the key in BOTH the crank and run positions. If it does, the yellow wire is not needed. If it does not have power with key in crank position, then you need the tellow wire also.

Replacement wire for the HEI (with correct terminals) you can get here.
