TR6 3-Prong TR6 oil pressure switch

[Brosky]

Does anyone remember the after market part number for the TR6 later oil pressure switch? I thought that I had it on the wiring diagram, but I don't. Actually, I think that it fits a Chevy Monza from the 80's as well.

And I don't want to go through the usual Q&A at the parts stores.

Hi, I need an oil pressure switch.

OK, you have the old one?

Yup, right here.

That looks weird.

People say that from time to time.

Year - 1974 - (eyebrows curl)

Make and Model - Triumph (eyes going blank, I'm losing him)

Wait, hold on, we don't sell motorcycle parts here

No, it's a car...really..

Sorry, can't help you. Try XYZ down the street who's even more clueless than me. Later, dude.

I was just looking at one on BPNW ( one of our supporting vendors) a couple of hours ago. I think they used the same one on Spitties and TR7/8's for the anti-run on valve control.

Phil,

I wanted to pick one up locally, rather than wait a week until it gets here from Oregon.

Paul, see if the "Monster List" is still up and posted. I had it linked to the hard drive on my dead computer and haven't gotten around to resurrecting the data off it.

Sounds like you're in the ball park, I vaguely remember Chevy also, Maybe someone like Buckeyes has the listing on it, or perhaps VTR.ORG.

Sorry I can't help you any more, right now.

Well found the URL for dimebank.

This is a good first step, I remember finding the crossover/interchange somewhere on this list.

HTH.

Napa Echlin part number OP6610 is supposed to be a direct replacement also 76-79 Chevy Monza and 250 cu in Chevy six cylinder supposed to work.
No personal experience with any of the above tho.

Also, to answer another post about the TRF part number for a 3-prong switch, there are some variations, so you need to check your commission number. The one for my Spit is GPS113.

This switch is plug-compatible with a standard GM switch, as used on 1979 GM models with a 5L engine. Olds Starfire, for example. Standard's number is PS-64. NAPA number is OP6610 (Echlin unit). $10.50 versus TRF's $24.95 and readily available at pretty well all engine parts places.

If you do a Napa search for "oil pressure switch" you will also bring up the links to their OP Switch sockets. Again, these are generally available from parts stores, in the range of $6-10. Makes it easier to get 'em off.

Thanks guys. The last one that I bought was the PS-64 and it worked well. I may try to get a socket to wire in there now that there is room to work.

Oddly, no matter what I did with the NAPA online, I couldn't get a Triumph OP switch. Just belts and other stuff.

Thanks again!

So, I have the NAPA OP6610 O.P.S., but have yet to install it... The 3 prongs are stamped I P S, in this configuration:

On the '74 TR6, there are 3 wires; a plastic plug, a black, and a purple. Can anyone confirm which goes where? TIA!

 

[Brosky]

Ray,

These are single prong according to my local NAPA, which I don't have much faith in. I'm going to stop in CT tomorrow and check it out there.

The three wires connected to the OP switch should be a) black - goes on the "P" terminal, b) a white with brown tracer - goes on the "S" terminal, and c) a white with purple tracer - which goes on the "I" terminal.

The black is ground, the white/brown feeds your oil pressure light, and the white/purple goes to one side of the A/R valve.
