[QUOTE="Yardsale , post: 1026489, member: 58988"] Two leads to the battery positive; no switch? There should be an 87 (normally open) and an 87a (normally closed). Connecting both to power will power the lights regardless of switch position. Electrical is much less confusing when using an actual schematic. Assuming the KC relay is configured the same as an OEM relay: - terminal 30 (high current for lights) from battery positive with a fuse before the relay - terminal 85 (low current for relay coil) from switch positive (3) with a fuse before the switch - terminal 86 to existing ground (4) - terminal 87 (high current for lights) to fog light positive - terminal 87a (for normally closed setup, as with the OEM high beam isolation circuit) assuming this is not to be utilized For an OEM switch, the wire on terminal 5 is for the switch background illumination (controlled by the dash lights dimmer). Also for an OEM switch, the wire on terminal 6 is for both the fog lights and the separate "On" indicator (internally wired). And a line to ground for the lights. [/QUOTE]
