fuel pump wiring & cooling fan wiring (SR20DET)

Recommended Posts

Monday I went to WGT Auto developments for abit of base mapping and everything was great, the only things I need to change is my cooling fan which is run off manual switch at the moment, but the tuner said to wire it directly into the ECU (it has the standard cooling switch).

And the other thing is the fuel pump, again I have got it on a flick switch but I need it to go into the ECU, positive wire I presume?

 

can someone explain how to wire them into the ECU wiring on a 76pin (4-3-3-3) SR20DET, is it just through the standard wiring itself on the plug?

ECU will switch ground to control both and they will require relays as the ECU can only switch 2Amps max.

Fuel Pump is on pin 18 in a factory set up.

Fan is on pin 19
