[fmanak72]

Aparently these are needed for my swap a Coolant Temp and Oil Pressure their are 4 sizes available from street and performance for both
12mm x 1/8, 12mm x 1/4, 12mm x 3/8 and 12mm x 1/2 sizes for the coolant and for Oil 16mm x 1/8, 16mm x 1/4, 16mm x 3/8, and 16mm x 1/2.

How does one figure out what size is needed.

i went a different route on my sensors.
i bought a single wire plug to use the factory oil pressure sensor.


& a 3 wire temp sensor, w/ harness to run both the ECU & gauge.


both of these are from a company i found on ebay.
