Relay identification

[JMAT]

I have a 1987 ranger with the 2.3 and tk5. I was wondering if anyone has a list of what the different relays are under the hood by location. I'm in the process of cleaning up my engine bay and just trying to get a good hold on what everything is. Thanks in advance.

Only 3
4 if you have air conditioning

Starter Relay(often mistakenly called starter solenoid), it's also the main power distribution point for the vehicle.

EEC relay, it will have a Brown base, it is a standard 4 or 5 pin automotive relay, when key is turned on this relay closes and powers the spark system, injectors and EEC(the computer).

Fuel pump relay, it will have a Green Base, standard automotive relay, computer grounds this relay to send power to fuel pump.

WOT relay, Black base, for AC only, this relay will cut power to AC compressor when driver pushes down on gas pedal to Wide Open Throttle(WOT), it gives engine more power with AC compressor off.


All the relays are usually on the same inner fender

1986 relays but should be similar, you can see black, brown and green bases for the different relays

The device on far left is a vacuum solenoid, computer activated, used for EGR system, EVAP system or ?? depends what you got

If you have power door locks there are two relays above the DS Headlight.
