Tacho takes it's feed from the alternator. Have to check your wiring & connections from there to the guage.

Reversing Lights - If you have an auto check the micro-switch on the shifter. If manual the switch is on the trans case. Also check the ground at the reversing lights.
Spots on low beam - need to change the feed from low beam to high.

The beeping comes from a small black box next to the shfter. Have to remove the console to get at it. The actual switch for reverse lights is on the shift mechanism - it's a small micro-switch.
If you have no joy, let me know and I'll take a piccy of mine.

Also, are you sure they are spots and not driving lights which would make sense that they can come on in low. This could be controlled by a switch on the dash. Just a thought ...

So sorry. Has been one of those months.  Follow the fat red wire. That goes to a relay I wired in to switch the lights. J |
