TI Wiring Harness

[Larry T.]

Is there an OEM version of the TI harness (perhaps a later service replacement) that the white wires to the coil and ignition were plastic coated instead of cloth braid covered?

Also, who makes the best (appearance and quality) currently available TI harness?

Thanks.

Larry,
If you are looking at your original white wire and it looks as if the jacket is a plastic coating check some of the wire inside the harness (a protective area). I found on my original harness that the exposed area does have a plastic coating on it now due to age warring off the cloth, that area protected from the elements still shows cloth. I used Lelectic Limited cable or you can check with tispecialty

Larry,

like Alan said check under the friction tape first to see if it's original. BUT you are correct the GM service harness had a smooth white wire. I have used Lectric limited for the T-I harnesses with good results. Although one of the terminals they supply is black instead of white that attaches to one of the wires from the distributor pig tail. So save your original to use.

Larry -- there WAS a GM service version (back until the '80s) that serviced all '64 thru '68 Corvette K66 harnesses by Jan 1970. As you can see below, the '80s version didn't have the cloth braid cover. This part # was also the production # for '68's (up until the pigtail-type amplifier began). Would be interesting to hear from others if their original '68s have the cloth cover or not.

This number 6295077, Gr 2.383 replaced the '66-67 TI harness 6289482 in service as of 2-69.

Re: TI Wiring Harness

Thanks guys. Wayne, the one pictured is the one I have. I will get with Lectric Limited to get a correct looking one for my 66. I am curious to as to whether or not the one pictured would have been correct for a 68.

Thanks,

Larry

Re: TI Wiring Harness

Way back when I was campaigning my 396, I took deductions for the TI harness on originality (from Lectric Ltd with vinyl tape wrap vs. cloth tape wrap)... The solution then was to buy from M&H who was the only game in town for originality in terms of cloth vs. vinyl harness tape wrap...

Re: TI Wiring Harness

Is that still the case?

Re: TI Wiring Harness

Beats me!

I experienced so MANY quality control issues with LL wiring products, that I switched to M&H exclusively. So, I have no idea what the configuration envelope is for the TI harness assy's they supply today...

Larry -- the only way we'll know is if someone reports in with what the '68 TIM&JG has to say, or tells us what type of insulation they have on an original. While we're at it, I'd be curious to know if C3 PRODUCTION K66 harnesses -- right through to 1971 or '72 have the cloth weave covering on the resistance wiring.

Consider also M&H, as Jack H. has mentioned.

Re: TI Wiring Harness

My 1970 original harness has the cloth wrapped white (almost yellow) wire in the TI harness. January 29 (A29) on the trim tag. Of course it has the pigtail wire on the TI, at least I think it does. There is no way in he!! to get in there to see. That amplifier is where the sun don't shine.

LL has the cloth tape. I have had problems with every harness supplier. It all depends on who you are comfertable with. M&H als make a good product as well as some off the radar mom and pop shops.

Re: TI Wiring Harness

After installation of the new harness a section of unused wire has to be wrapped with the cloth tape. If anyone has a good photo of what this should look like please post it. Any tips on proceedure would be appreciated as well. Thanks

Re: TI Wiring Harness

Steve check your AIM. The 64AIM does not show any tape, however I do recall finding a reference someplace about the tape and did add to mine. It makes sense since a lot of extra wire is floating around once TI is added. Would also like to see an Original picture.

Steve,

Just to clarify, are you referring to the unused pink coil/resistor wire that is cut and taped back to the harness? Or how the harness itself is actually taped and where the tape stop and how it it ends.
