LT/LS Swaps / motor mount question
« Last post by revevans3 on May 12, 2025, 10:45:29 pm »
81 short bed, 5.3LS, 4L80e. I'm having trouble getting my pinion angle correct as my 4L80 is up as high as it will go and the angle is still out by 3-4 degrees. I'm currently using ICT Billet motor mounts and wondered if anyone has a suggestion for lower profile motor mounts?  Thx

As long as power reaches the headlamp switch, it distributes that power to the various running lamps (except for the brake/turn lamps, which are powered through the turn signal switch).  The headlamp switch has two power inputs: one strictly for the headlamps via a fusible link, the other for all the running, dash, and cabin interior lamps via the fusebox.  The issue is probably inside the cab if you don't have power through the firewall bulkhead connector.  Verify power to the headlamp switch, then check power on each switch terminal.  If the switch operates properly, move to the wiring between the switch and the bulkhead connector.  Follow the links I provided; all of the information is there.

Did some testing on the rear wires out of the left driver's side block with not much luck, traced wires over tank and lost them, but everything looks solid.

How big of a part does the light switch play in all this wiring issues?

Sitting for that long the problem could be rodent damage.

Verify power on the rear lamp wire harness where it exits the firewall bulkhead connector along the driver (left) side of the connector.  If you have power there the fault is rearward.  Typically, the rear lamp wiring runs through corrugated loom along the left frame rail.  Wire damage/separations can be difficult to locate when hidden inside the loom.  Be patient.

If there is no power through the bulkhead connector, use the diagram of the headlamp switch connections (previously linked) to test power through the pins of the switch.

No power at rear on anything but left blinker, no power marker lights. Bulbs are correct...
