4 pin relays for headlights

Connectors I used at the headlights are rubber booted, 90 degree, low profile, ceramic. This is for 7 inch round aftermarket fixtures with H4 bulbs. Expensive change there since the connectors came with undersize wire of wrong colors. I found new quality terminals that would accept my 12 awg.
Connctors at my relays are plastic. Wire line in out is 12 awg. Fuses for line in out are 20 amp. Wiring to relay coil is factory ( 18 awg I think ). Fuses to relay coil are 10 amp. These 2 fuses are inside the car, inline between headlight switch and dimmer switch.
