Still working on installing the new Sniper EFI purchased from IH a few weeks ago. I need to find a location for the coolant sensor and the only location I see on the manifold is where the stock sensor goes to the temperature gauge in the dash. Any ideas on where else I can install it? Looks like 3/8" threads. By the way, this is a '69 800A with 304.
 
years ago when i had fuel injection- i had mine in the back on the intake there is a pipe plug that goes to a water jacket.

i can get a picture if you like my temp sensor is still there.....

Thanks there are 2 plugs back there on the 1969 304 but I thought both of them were for vaccum, which has long since been removed. Unfortunately I can't find anywhere yet if either of those plugs is for coolant to be sure.
