Which relay switch? Photo.


Recommended Posts

The tachometer (in the dash) uses the yellow wire off the ignition coil to get its pulses. The fuel pump control module also looks for the pulses on the yellow ignition coil wire in order to see if the engine is running, to cut power to the fuel pump if it's not.

Those 4 relays are

 

From left to right

 

Defrost

Blower motor (heater)

Headlamp R

Headlamp L

 

None of them should be messed with for EJ swap.

 

 

Second pic.....Fuel pump control relay.....

 

Attach your EJ tach wire to the Yellow wire at that connector

Attach your IG. Switch power "on" the EJ harness to the Black/white wire at that connector.

Attach your EJ fuel pump power out (from EJ Harness) to Blue/red wire at that connector.
