d. Cab Upper Wiring Harness (Cont).
INSTALLATION (SHEET 1 OF 4)
Spray all terminals and contacts with electrical cleaner and allow to
air dry before making connections.
Using electrical tape, tape new cab upper wiring harness three wiper
motor wires to a 16 feet long piece of wire. This wire will be used as a
fish wire to fish new wiring harness through left front and rear posts.
Using electrical tape, tape all cab upper wiring harness branches to main
branch. This will make it easier to pull harness through rectangular hole
in cab rear wall and up through left rear post.
Guide cab upper wiring harness through rectangular hole in cab wall and
through left rear post while assistant slowly pulls it using fish wire
taped to harness. Tell assistant to pull on fish wire from top of left
rear post not at front windshield.
When cab upper wiring harness is completely through top of left rear
post, remove all electrical tape from branches except branch containing
three wiper motor wires. Push harness connector firmly into its rectangu-
lar mounting cutout in cab wall until it snaps into position.
At front windshield, left post, tell assistant to slowly pull fish wire
through hole in post while you guide harness branch down into post.
