Topic: firewall grommet for non-AC blower motor

[rare70cat]

Anybody have a part # for the firewall grommet that the blower motor orange wire goes through? Does it have a slit for installation? Thank you

You didn't include where the car was built but given the screen name I'm guessing Dearborn.

Few examples where the firewall sealant was not applied too heavily in the area.

Thank you. Good guess on the car. 1970 Cougar. The pics I found I couldn't get close enough to see if there was a slit. Maybe the same grommet for the brake line at the shock tower? Thats what it looks like in the bottom right pic. My orange wire actually has a three inch cloth section where the wire goes through the firewall.

Kind of looks like a repair there

Ahh sheet man don't say that! Now I'll have to look! If so, I'll have to take that b-otch back out!!

Unwrapped the two cloth tape areas at each end and there was a cloth sleeve in the middle. Slid the cloth sleeve out of the way and there is No damage anywhere! It had to have been done by the factory? You can't slide the cloth sleeve over the square connector that plugs on the heater box resistor either. So I'm going to put it back. Good thing I have some new cloth tape from AMK. I will take some better pics today now that's its daylight to try and show some detail.

The use of a grommet for the fan motor wire is not apparent in the "1970 Mustang Electrical Assembly Manual" (AM0033) pg 45, view A, for Mustangs, or Ford Car Parts (aka MPC). The wire appears to go thru the fan mounting assembly.
For a replacement grommet, get the measurements: the hole in firewall diameter, hole for the wire diameter, assume 0.060 to 0.090 inch firewall thickness, and then try Lowe's. I had good luck there when I needed a grommet.

Here's a couple more pics with better detail. The thing is I pulled the wire up to the hole and the Cloth wrap section doesn't make into the hole!

jcw66k, that would make sense for the cloth sleeve to protect the wire going through at the blower motor. My car was built in November '69.

Got this pic from the 1970 Car Shop Manual volume three electrical. Mr. Speegle, have any pics of this arrangement? Thanks

The grommet that goes in the shock towers for the brake lines,works for the heater wire prefectly,one of the guys on the Boss regristry stated it a while back. Muscle car research sells the said bushing. I put one on my Boss, sweet,I was looking for a year .Greg

Power wire for the heater motor run/tapped to the heater motor and traveling along the top of the motor into the interior?   No

Doubled checked for you unrestored cars from very early production (Sept 69) to pretty late (July 1970) Have about 4.5 G of pictures representing 1970 details if I went through every one.

I find Shop Manuals very unreliable as far as illustrations and pictures go. Great for text to help you repair things if you can't figure things out but pictures are often borrowed from other applications or they show preproduction drawings and illustrations since they were often created before production started so that shops would have help from day or or so of regular production

 How do you explain the cloth sleeve? You thought it was a repair. There was No damage on the wire anywhere. That cloth sleeve had to be put on the wire before any connectors. "Curious minds want to know".

Don't no. Guess if not for repair would be for chafing possibly
