[86lxhatch]

Do you know what color these wires are under the hood on an 86 lx hatchback?

1. tach signal wire color

2. oil pressure sender wire color

3. coolant temp. switch wire color(the one that tells the gauge in the cluster how hot the car is)

The 86 EVTM shows:

Oil Pressure W/R
Coolant Temp R/w
Tach DG/Y
