3 wires that route across the front of the block

[s13b]

IIRC they all part of the main engine harness.

All 3 of mine have worn badly due to the shat route the last guy who installed them took, so need to order replacements.

Question is what 3 wires are they?

1 is Crank position sensor

What to the other 2 do / control?

I'm not near the car so cant go out and look!

Thanks

CID (Cylinder ID)
Oil Pressure Switch

Three wires? I'm pretty sure the engine I'm working on now only has two, the oil pressure switch and the CPS. Did all cars have a third?

edit: Is the third the one that should run over the top of the upper timing cover?

Cheers, I haven't fitted the HT leads yet so that would explain it's absence.

Only the oil pressure switch wire is part of the engine loom, and is only a single wire. Other two wires are part of the respective sensors.
