H4 relays installed in '66 - Am I doing this right?

[dondarnell]

I bought this harness on ebay to convert a car to H4. I have it installed in the front, but I am wondering about how to integrate it into the harness. The wires that from the block are yellow in (the fuse block) and yellow out for low beam, and white in white out, both sets to the lights (one for each light). The harness that I purchased has two relays, one with a red wire and one with a white wire, just one for each to the block, then two out to the lights (and a black ground and red wires to the battery).

Am I correct to assume that the relays are one each for high / low beams? And that if I merge the two yellows and the two whites with the corresponding single wires to the relay, the system is complete?

I am attaching a photo with that shows the relay, and wires to three prong plug, which I intend to cut out.

You see two additional wires heading back because they are the power wires that I am going to join to a junction box.

typically yes, with a 2 relay system each relay controls either dual low beam or dual hi beam. well that is the way it is setup on my 83SC so things may be a bit different for you.
