switch sizes?

Hey guys,

Just need to know what size the following things are cause i need to buy some fittings for some gauges tonight:

Thermofan switch
Oil pressure switch

I had a look at the thermofan switch last night (without takin it outta the engine) and i think its a 1/2 inch. haven't had a chance to even glance at the Oil pressure switch yet.

The engine is a B16A2.

Thanks for the help guys & girls.

You need senders not switch's so your gauges function. To run the oil sender you will need a sandwich plate,with the temp gauge(assuming what your talking about,dont see how/why you would need a gauge for thermo fan?) you can tap into the oem sender.

Hey Jase,
Now I just measured up my Old fan Switch.

I am pretty sure its M16 x 1.5

Not sure about oil pressure sender.
Hope that helps.
