I have an 83 Gl wagon.It has a EA81 with a SPFI conversion.A while back I started having proplems where the car would just die on me for no reason. So I pulled the dash and the harness. So I could fix the harness and better mount my ecu. Turns out a wire on the engine side of harness had slipped out of its wire loom and rubbed a hole through the insulation.

 

anyway for as long as Ive had the car several relays have always been dangling from the dash above the pedals,so while the dash is out its probally a good idea to remove some of those relays.

 

First up:

 

second one,it has a mitsubishi logo on it:

 

third:

 

and finally the forth:

 

all of them are near the pedals or steering wheel.Thanks in advance.

Just unplug them one at a time, then check to see what works and what doesnt.

Kind of like common sense.

#3 looks like the turn signal flasher relay

 

#4 looks light the headlight relay

 

Not sure about 1 and 2

There you go being logical again.

I wouldn't have been able to test stuff because the car is apart. the dash and all its switches is in the back seat, as well as the instrument cluster.

 

BUT, I found out that #1 is the seat belt warning system from orielly auto parts web site.

 

#2 is the fuel pump control unit,but my fuel pump is ran by the relay on the SPFI harness.

 

#3 is the turn signal relay.

 

and #4 is the headlight relay according to crazyeights

 

so 1&2 get nixed.

 

thanks everybody.

#2 is where you *should* have tapped into the tach signal and the fuel pump power supply lead for the SPFI's harness. It's the easiest place to access those.
