What are these 2 wires 1974 Roadrunner

[flamesoldier]

I cant figure out what these wire connections are for. See pics
1st one yellow line going halfway down fender.
2nd blue and green connector coming out of firewall.
3rd black connection on driverside light area

The first picture, yellow wire , looks close to the windshield washer pump motor. Just a possibility based on nothing else but the location of the wire.

The harnesses seems to be pretty much manipulated.

1st pic, yellow is starter relay Ign prong. Longer that it should thought… are you sure is 74 harness? 71/72 gets this wire reaching the side of the batt, due the starter relay location. 73/74 relay is just right abive the brake booster.

2nd pic, if coming from firewall throught a grommet… AC harness

3d… dunno, but I think your forward light harness could be not the right one based on your other thread and the yellow wire

CAUTION: If you connect that wire to there & that wire to over there... when you press the horn button the engine will start.
hmmm??
