What wire color feeds the trunk light on the 1987 LTD Crown Victoria?

The trunk light is fed by an LT GRN-YEL wire from Fuse #3.

What resistance values are used in the steering wheel cruise control switches?

The steering wheel switches use 2,200 Ω for RESUME, 120 Ω for COAST, and 680 Ω for SET/ACCEL.

Which fuse powers the hazard flasher circuit?

The hazard flasher is fed by Fuse #1 via an LT GRN-RED wire; the directional flasher is located in the fuse block on an LT BLU wire.

What wire colors go to the rear directional (turn) lights?

ORG-LT BLU goes to the right rear directional light and LT GRN-ORG goes to the left, with the same colors feeding the trailer directional light relays.

What wire color runs the taillight and marker lamp circuits?

BRN (brown) wires feed the right/left taillights, rear marker lights, front parking lights, coach lights, license lights, and trailer exterior light relays.

What wires connect to the cruise control amplifier?

The cruise control amplifier connects to BLK (ground), LT GRN, WHT-PPL, DK GRN-WHT, GRY-BLK, WHT-PNK, ORG-YEL, YEL-RED, PNK-LT BLU, and BRN-LT GRN wires, with the cruise control servo shown as a 50,000 Ω unit with vacuum and vent connections.
