Starter Relay Wiring?
So I’ve got a factory starter relay now and have some time to switch it out with the aftermarket one – but there be a problem. The wiring diagram in my Haynes manual doesn’t match the wire colors on the relay I have. I have one from a 1985-89 Toyota P/u 4Runner w/ 22R or 22RE part number 28300-35010.
The wiring on the relay is as follows:
1 White with Black stripe
1 Black (no tracer color)
1 White (no tracer color)
1 Black with White stripe
But, to make things slightly more annoying where the connector is the wire colors change to . . .
1 White with Black stripe becomes – Black with Red tracer
1 Black becomes – Black with White tracer
1 White becomes – Black
1 Black with White stripe becomes – Black
Also, theses last 2 merge (via a factory looking connection) into one Black wire.
Does anyone have a simple answer to . . . Which one should be wired to where?

the 2 black wires that merge go to ST1 at the ignition Switch.
which makes the relay sort of dumb idea as both the coil and the contact voltage come through the ignition switch
The black white wire goes to a Yellow connector (86) turns black and goes to the starter solenoid when the relay pulls in
The black red wire goes to the clutch switch at the pedal if this is a 4 runner it also tees to the clutch cancel switch on the dash
this is how the coil grounds
Just curious why you are not doing the fix to not run the starting voltage through the ignition switch ??
on the relay just run the incoming voltage direct from the battery your plug might be different but on the 86 it is pin 4

This is for my ’84 Pickup, so no clutch cancel switch. I already have an aftermarket relay wired in (temporarily) because I want to use that one for the headlight relay. I’ve got the Toyota starter relay now and want to put that in but the wiring of the Toyota relay I have doesn’t match my Haynes manual wiring diagram. Also, the Toyota relay isn’t marked with 86 and 87 etc.

The 86 was the year of the EWD I was using
It should be a simple matter one wire should come from the ignition switch this energizes the coil the other coil pin goes to ground
from the factory the contacts got voltage also from ST1 this can be wired direct to the battery the other side goes to the starter solenoid
If I remember I will look at a Starter relay when I get home from work
