And the 550F diagram:
In the bottom left section of this diagram is the LH control, labeled "headlight dimmer-turn signal switch".
Can anyone help me read and understand the tiny abbreviations?
B = buzzer? (I'm eliminating this)
Lo = Goes to white wire, so Low beam
Hi = Goes to blue wire, so Hi beam
HL = Goes to Bl/Y, which goes to the headlight fuse on the fuse box, so headlight power?
R = Goes to LB, which is RH turn signal
L = goes to Orange, which is LH turn signal
W = Grey, goes to "winker relay"
PR = LB/W, so that's the "parking light, right" or the RH running light (won't be using)
PL + O/W, so "parking light, left", or LH running light
TI(?) = I think that's an I. Brown/White, goes to ignition switch. Turn Indicator power?
H = horn
E = earth? It's a ground, with no wire color showing.
If I can identify and eliminate the running lights and the buzzer, I have all of the other wires connected properly.
I just need to identify what the BLACK/RED and BLACK/Brown are for.
