dual ballast pic

[noschevys]

Does anyone have or can they take a picture of an original dual ballast setup on either a 71 or 72 challenger or cuda that shows the wires when used with the original 5 prong ecu .   Thanks, the picture would answer a bet.

Don't think they had ECU's in '71

the first year for electronic ign was 72 as an option & 73 on all models , if you have a 4 pin ECU do not worry about using the 4 pin ballast , the 2 pin will look more correct

Here's my '72 Challenger setup before I replaced it with an MSD box.

Thanks.  I think I won.  Is that a light blue wire on the side of the black? jumper wire?

They all look dirt colored to me!

The wire with the jumper is supposed to be dark blue.
