Originally a TI car?

[Michael G.]

Good evening all,

• Would a hole be drilled into the firewall for a ballast resistor regardless if the car had TI?
• Is the wiring setup described typicall for altering a standard ignition to TI application?
• Any way to determine if car was originally a TI car?

Would hate to convert car back to a standard ignition if car is a TI car .

Thanks

Re: Originally a TI car?

Michael, there was a discussion awhile back on the ballast resistor hole, from all accounts it seems that the hole was there on all cars, TI or not, but a dab of some sort of goop was smeared over the hole if TI was ordered (which in most cases could/would fall off over time). Does it look like there was ever a screw in that hole?

Michael -- here's a link to such a discussion, which contains prior link to another, all around November 2008.

Re: Originally a TI car?

Look at your K66 section of the AIM. On the K-66 section, sheet A3 at the lower left of the page, it shows an extra wire retainer added to the underside bolt holding the drivers side hood catch to the front of dash. That is the one item generally missed in a conversion from std ign to TI. Does your cad have the clip? If so, likely a factory install. If not, likely a std ignition car.

Re: Originally a TI car?

I remember the thread Wayne linked to, and recall researching my references for that hole. There is no callout either in the Chevrolet Assembly Manual or in the A.O. Smith Process Manual to drill the ballast resistor screw hole in non-T.I. cars, which leads me to believe that the resistor hole was indeed in all dash panels from the molder. This was a "base car" item, and would have been shown with a grid location and hole diameter to drill had it been required.

William, on your AIM copy, can you make out the revision record at the bottom? I'm curious of the dates listed, mine is not legible in that area.

Thanks,

Re: Originally a TI car?

The release date is May '65, the revisions are unrelated to the item in my comment. Revisions are 2-1-66 and and a later revision calling out an optional coil

Re: Originally a TI car?

Ok guys.....so far what I'm hearing the hole would have been there regardless.

Now for the image of the connector wire in my post. This wire came through the firewall from the dash harness (have since pulled original harness) Was it SOP for the production line to clip off the original dash harness wire with a lead appropiate for a ballast resistor and then wire in a lead for TI?

btw....no hole below drivers female latch where clip would have been.

Yes, the original terminal was removed, and the TI terminal and plug was installed. There was no splice in the wire if thats what you were asking.

Michael, out of curiosity, approx. when was your car built?

Re: Originally a TI car?

I understand what your saying "there was no splice" however you see what I had. May have a correct TI connector but you can see the wire had been spliced. Confusing at this end .

The car is A.O. Smith built on 9/23/65. Thanks.

Re: Originally a TI car?

Michael,

Correct me if I am wrong but I don't think Bill Clupper is talking about a hole at the firewall hood latch but a U shaped wire hanger attached to the lower bolt securing the latch assembly.

I think I read somewhere that early cars were spliced for the TI ignition..

Re: Originally a TI car?

I am going to post twice as I need to upload more than 4 pictures. Attached are three pictures of the amp box holes on the left fender. The first one is 66 425 HP #210XX survivor car, 2nd is 67 435 #12676 and 3rd is 67 435 Bowtie #19XXX. I have had many of these cars pass through my hands..some with the box and some without but holes showing. Everyone was installed like the first two with the 9:00 hole of the box being one inch from the hole for the park lite plug and north/south centered on the park light plug. I have a dozen pictures of this placement in my files for 66 and 67 cars. The 3rd one shown is the first one I have seen that is not centered on the park light plug but is a well know 67 survivor car in the 19000 range. All three are St. Louis cars. The poster's holes look placed dead on for a real TI car in my book.

I think Bill is referring to the clip shown in the extreme right thumbnail of this link's post #1. The original T.I. harness is still held by this clip.

Doesn't apply to '65 L78 as the T.I. harness went down the passenger side; however I wonder if this clip was added from the 'git-go' for the '66 model year (yours is a real early car) or later, given all the '65 under-hood stuff that carried over to the early '66s (just thinking out loud ).

Re: Originally a TI car?

I do not have my books with me (am wintering in Florida from PA). I think the use of the TI clip under the LH hood catch started in the middle of 1966 production. Maybe it is specifically stated in the AIM. I know 66 vin #18XXX had it and seems that it was not on 66 VIN 9000ish. I have never seen a 67 without it (or the hole for it). It was not placed precisely but in a general area under the catch to help hold up the TI wire harness...looks like it was just quickly drilled and attached with a hex screw. The four pictures attached are all 67 435 cars. Maybe some others can check their original cars and verify. If the original thread starter has an early vin and no hole, this could be the reason.

Re: Originally a TI car?

Two points, however these are based upon a Mar64 car;

No splice of wiring in harness.
No hole or indent for resistor.
