Since I changed all the lights over to LED, new flashers were needed. These came in from SuperBrightLEDs, and should hopefully make them all function like stock. HD ones were ordered for the additional load that trailer lights add to the system. Black is for regular turn signals, red is for hazards. Just FYI for anyone else doing LEDs, the flashers are wired at different polarities at the flasher terminals on these Chevy trucks, and will cause issues if the flashers don’t match. Hence the need for two different flasher units.



Summit also delivered more fire sleeve for fuel lines, solder connectors for a few more bits of wiring remaining, and the fuel pressure sensor wiring extension so I can safely mount it to the fender instead of the engine.



I also picked up a headlight switch which I had forgotten to order earlier.



Headlight switch installed!



Flashers installed in the fuse block!



Extended the ground wire for the fuel pump relays, and changed to a ring terminal.



Under dash grounds finished!



I also ran the secondary ground wire for the fuel pumps themselves. This interties with the ground wire near the switching valve, to eliminate any chance of grounding issues with the pumps!
