66 327/300 convertible with factory AC wiring question

[Paul M.]

There is a heavy red wire with an in-line fuse (35 amp) attached to the blower relay and comes out of the wiring harness about 6-8" from the coil on the passenger side. After it exits the harness, there is about 3' of wire with a large eyelet at the end. I know it is the hot wire to the relay, but I need to know the correct location to attach it. The starter seems to be the logical place, but the 3' of wire seems excessive. It will reach the battery, and the eyelet is big enough, but I'm sure it didn't attach there. I want to get it in the proper location so I don't have to do it again later. If you know where it connects, I would appreciate an answer. Thanks, Gene

That goes to the horn realy. It's all shown the AIM under C60 and in your service manual

The red wire will reach the battery but is way too short to reach the horn relay on the radiator support. As I said, it exits the harness about 6-8" from the coil on passenger side. I would thought they would have left it inside the harness and ran it along the driver side fender if it was going to the horn relay. I'll check it out in the AIM tomorrow under C60. Thanks for the info!

That wire confused me also .I know I couldn't find it in the AIM .Here is what I did with it. I hope it's correct ! If not, I am sure we will hear from someone !

I honestly don't remember how I came to that conclusion.I think I traced it down from the electrical wiring diagram.

Thanks Jim! Looks like you connected it to the solenoid which seems logical. My electrical diagrams don't show it, but I will take Keith's advice and look under C60 in the AIM. I just want to get it wired correctly. Gene

Gene ,

Good luck ! I could not find it there.

I remember now how I came to place it on the Starter Solenoid. I called M&H , the guys who made my harness, and asked them where it went .

If you find it in the AIM let me know where .

If it helps, I have DocRebuild's pictorial wiring diagrams. The 66 Headlamp & Ignition Harness has a separate A/C diagram and shows a fused (35 Amp) red wire that runs from the AC Relay connector to the Horn Relay (round connector as you describe.)

The AIM shows it on F295 (C60 E9) running to the Horn Relay like Keith and Don said. I bought my car in 1967 and I know it has the original harness in it and it didn't connect to Horn Relay. A friend told me today that his 66 327/300 AC runs to starter. I'm relatively sure that is where mine connected originally, so that's where I'm going to put it. Thanks to everyone for their input.

Gene,

Thanks for the info . My 66 AIM (C60 E9 ) is page 329 ? I see what they are talking about . However like you , I am sure it didn't go there . In fact it couldn't . Perhaps someone with a 67 AIM can show us a revision of that wire placement that didn't show up in 66 , even though it was apparently changed.

My car was built on Nov 12, '65, so they may have changed the harness later. Mine is currently resting peacefully on the solenoid.

Mine too . I hope we don't blow up !!!

67 AC harnes lead with the inline fuse goes to the horn realy. Don't forget to upgrade the fuse in the fuse block as well For AC cars the heater fuse is heavier then called for on the fuse block

Thanks Keith ,

Ok then ! Lets hear from a 65 Aim owner. Maybe the change was called for in 66 but didn't start until late 66 or 67 .

The '65 and '66 A.I.M. sheets don't show that red power wire (except on the A/C wiring diagram page), but it DOES show in the '67 A.I.M., in section C60, on sheet E1; View "C" specifically shows the connection to the horn relay, and the main illustration clearly shows the wire (item #1) routed from the blower relay on one side, across the cowl, and forward on the driver's side of the engine compartment to the horn relay.

John,

Thanks for the response.

We must be talking about another red wire then because this one would never make it . As Gene stated in the start of this post " it comes out of the wiring harness about 6-8" from the coil on the passenger side" . I have enclosed photo #1 . He goes on to say " After it exits the harness, there is about 3' of wire with a large eyelet at the end ". I enclose Photo #2 .

This same wire along with a long black wire that also has a large eyelet and comes out of the same place in the A/C harness ,as you can also see in photo #1 , had me wondering, and I posted the same question on this forum a while back. I think I requested some photos of wired starters as I assumed it went to there , but couldn't find anywhere in the AIM to tell me that . I did get some great photos of wired starters , but none with my extra red and black wires in them . So since I never did get an answer , I finally called M&H and they told me they went to the starter so I put them there . I still couldn't find anything in the AIM that confirms that placement , but I know it would never make it to the Horn Relay . Not even in a straight line across the engine !

So all new facts in hand , what do you think now ?
