Headlight relays need help with them

[oldblue1968chevy]

Im about 1/2 way done. It wont be clean but the next one I'll do will be now that I know how.

Do I run 2 wires from the battery to the relays? or can I tie the 2 post on the relay together, then put 1 inline fuse before the battery?

Do I have to use 2 fuses?

And is 85 on both relays ground?


1 Read the artical
2 Parts list 2 bosch relays, spade connecters, wire, and inline fuse.
3 Look at wiring sheet
4 Decide that you can do this
5 Start by finding the 14LG and the 18LT wire on the back of the left headlamp.
6 Disconnect the (-Neg) battery cable. Mount the relays to the core support above the horn. You may have to make room for them.
7 Follow the 14LG wire towards the fuseblock. Mark it. This is the one to cut.
8 Follow the 18LT wire towards the fuseblock. Mark it 1st. Cut this one also.
9 Do the wiring:
cut 18LT (or low beam) and run the wire from the fuseblock to Terminal 86 on the relay.
run the other end and that comes from the headlamp plug to Terminal 87 on the relay.
cut 14LG (or hi beam) and run the wire from the fuse block to the Terminal 86 on the 2nd relay. run the other end to Terminal 87 of the 2nd relay.
10 Terminal 85 goes to ground.
11 Run a heavy wire (12ga.) from + Battery Post to Terminal 30 of both relays. Just run it through the stock wiring across the radiator. Add a inline fuse on this one.
12 make sure every thing is connected, secure wires,
replace (- battery cable )
13 Enjoy Brighter Head Lights

^Thats what Im going by.
