Good to know. I used the upper one and the oil temp I'm getting at the filter block with an "inline" fitting. Thanks for your help.

No sh!t Well I ditched that stuff sooo......Thanks for the input.

Left one coolant temp sensor to gauge.
Right one coolant temp switch for overheat alarm.

That's actually a really good setup you have there. Probably make some good money back off of it or keep it as a spare for the MSD.

Left: Pressure switch for alarm. Usually for oil psi.

Right: knock (detonation) sensor

yep as Rookie stated if you pitched all that you pisssed away about 300 bucks

I "ditched" not "pitched". I have it all in boxes.

Thanks SB. Now I know what to keep and where to install. Thanks again

So I stripped out the brass plug above the oil filter location at the block. The socket on the plug, not the block. Anyway, I would still like to have the alarm go off for low or no oil pressure and am wondering if I can install the sensor at the filter head? I would assume if this will work that I would NOT install it where the arrow is pointing in. If there's another location please let me know. Thanks for the help.

Is brass plug a allen head or hex head? If it's and allen put a punch in center of the plug and hit it a few times with a hammer. This will shock it loose, then drive a bigger allen in and remove the plug. If it's a hex head get a "turbo socket " and remove the plug.
