switch

Does anyone know where the reverse light switch is located on a T-150 transmission? Also, is this also the neutral safety switch?

IIRC-the '150' didn't have one.

There are two switches on the transmission shift tower.
One would be for transmission control spark (emissions)
The other is your back up light switch.
No such thing as neutral safety switch on that year/model.
You have to use your brain.

On a 1978 T-150 there is a reverse switch on the top just behind the shifter. If you take the tunnel cover off you should be able to see it. I don't recall seeing a neutral switch and there is no spark control switch on anything that early.

TCS (transmission control spark) has been around since at least 1973 on Jeep manual transmissions. (at least in California)

You sure about that?
My T-5 has no such device. Nor have I ever seen any such thing on any Jeep's T4/5. My Jeep was bought new in 1985, and is a CA. model.
The ONLY electrical device on my T5, is the reverse/back-up light switch.
Nor did I see one on the T-176 I just help pull out of my friends 81 ca. model CJ5.

Lumpy, i'm thinking that the TCS went out when the computer controls came in.

I can't see/find it on any T-150 'exploded view'. Do you have one that shows this? My 'puter search foo sucs at times.

Switch for SR4 T4 T5 are all on the transmission case if I recall correctly.
TCS switch disappeared
beginning in 1980 with the advent of computer controls as previously mentioned.

You did not note which trannys had this-
On the T-150. Which switch is which? I think the 2 pole switch(3.319-2)would be the back-up light switch as it looks like the one I have on the T5.

The back-up light switch is on the right side of the T4/5's used in Jeeps.
The switch does fail often. I keep a couple of spares on hand.
