Question PSI3/DEFI

need some advice connecting oil temp and pressure sensors to a PSI3 unit(one of the later versions)

do i need a defi oil temp kit and defi oil pressure kit?

also would i be right in saying i can connect both these sensors to a scoobyworld sandwich fitting plate?

tell me if im wrong and any other advice is much appreciated

thanks in advance

Ive just done this to my hawkeye. You need the defi oil pressure and oil temperture sensors and harnesses.

You dont need a sandwich plate, you can remove the existing pressure sensor and replace it with the defi one. You can fit the temperature sensor above cylinder 3 by removing the bung in the block and replacing it with the sensor. You do need a adapter bolt for the sensor.

I bought all my bits from AS Performance in Birtley.

the sensors and harnesses they come in kits don't they?

I've heard of some people keeping the existing pressure sensor in and using an adapter to fit the defi one in aswel, so I'd like to try and do it that way if I can.

what do you mean about an adapter for the temp sensor?

I'm also doing this to a hawkeye

You don't need the existing pressure sensor all it control is the oil light, but it only works at 0.2 bar of pressure, by then your engine has possible gone. The adapter for the bung in cylinder block is just because the thread is much bigger than the defi sensor.

Also just wondered did you have any trouble wiring the defi sensors to the PSI3?
