Suba_GL_87 Posted July 19, 2014 Share Posted July 19, 2014 I'm not sure which is relay switch. Fuel pump relay, ignition relay, kick down relay. Number 2 photo; it's ignition coil? Let me know. Thanks Quote Link to comment Share on other sites More sharing options...
BirdMobile Posted July 19, 2014 Share Posted July 19, 2014 (edited) #2 photo is definitely the fuel pump control module. I have a thread going about its wiring. . . Edited July 19, 2014 by BirdMobile Quote Link to comment Share on other sites More sharing options...
Suba_GL_87 Posted July 19, 2014 Author Share Posted July 19, 2014 Oh ok. I thought its ignition coil... but Where's tachometer by the ignition coil? Quote Link to comment Share on other sites More sharing options...
BirdMobile Posted July 19, 2014 Share Posted July 19, 2014 (edited) 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. . .

BirdMobile Posted July 19, 2014 Share Posted July 19, 2014 Here's my thread about the fuel pump control module: http://www.ultimatesubaru.org/forum/topic/147752-ea-82-distributorcoil-voltage-question/?do=findComment&comment=1240253 It is about the distributor, coil, fuel pump, and module wiring.

Suba_GL_87 Posted July 19, 2014 Author Share Posted July 19, 2014 (edited) Thanks. I just need to know what's relay switch of four them. Before to ej22 hardness hook up. Edited July 19, 2014 by Suba_GL_87 Quote Link to comment Share on other sites More sharing options...
Gloyale Posted July 19, 2014 Share Posted July 19, 2014 (edited) 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. Edited July 19, 2014 by Gloyale Quote Link to comment Share on other sites More sharing options...
