Quick Engine Harness Question
« on: October 20, 2014 - 10:01:15 PM »
Hey gang,

Swapped out the 318 for a 440 6 Pack recently in my 74 challenger. Just got the engine harness. Let me preface this by saying that we had a good long chat with the guys and they suggested going with a 74 small block harness, as that would plug right in, with the exception of a few wires that we'd need to modify. So just about everything lines up with the exception of the attached....cant for the life of me figure out where this goes. Any Ideas/suggestions would be awesome, thanks!

I'm guessing it's for the seat belt/starter interlock only found on '74 E-bodies, couldn't find it on a schematic but my '73 has nothing like it.

Yellow wires or a tri plug under hood is just weird , yellow was used for interior  dome lights
