Any difference between 72tii and 73tii front wiring harness?

That boot is good enough for me...thanks for the reference. It's not exactly like the original one though, as I recall...the original boot had tabs on it similar to the cold start boot. Actually, that boot looks very similar to a boot I bought for the alternator on one of my other cars. I'll have to check p/n's.

Guys, Marc Caden found a boot that fits that connection like the original, I have posted that part number before.

Let me waddle to the shed to see if I have a spare in the bag and will report back.

Here we go, I use this on the thermotime switch

The part number for the cold start/fifth injector is 61 13 1 352 793

Randy, do you have the part number for the sleeve from McMaster Carr?

By the way, Wuth has STILL NOT called me back.

Good info...thanks!

John - the cold start valve boot is available from BMW - under the E9's I think. I got mine from Rob Torres along with some other parts.

John, you are correct about the original boot having "ears".

And the angled connector on the temperature sender looks insulated. Maybe use some brush on "Plasti-dip" coating on a new terminal???

Yup, that's the one! Thanks Bill....that original OEM boot "with ears" came as a "one piece" setup along with the wiring (harness)...this is the part I lost, sadly. Very rare to ever find one these days.

Round and round we go - but this is my kind of fun!

The boot kind of looks like the one on the electric fuel pump (but that one has two holes for the wires). Note the Bosch part number. When I google that number, I got a hit to a Citroen DS21 fuel injection manual. The Bosch pump used in that car uses the same rubber cap (and maybe the plug and cold start valve) used on the tii's. Sadly, the fuel pump has (3) fuel fittings on it just like the pump used on the VW Type III cars (Fastback, Squareback and Notchback).

Jim, are you saying the boot with "ears" is available?

[jgerock]

No. I'm just saying that those two boots look identical. I have been searching for the right boot on multiple websites - nothing yet.

Edit - here is a close up picture from the BMW Fuel injection manual. I see the angled wire terminal for the temperature sender is not insulated.

And a good picture of the # 4 fuel injector on a 72tii engine
