E.g. can't find the turn signal circuit anywhere.

Prospero's Garage has a large laminated CS wiring diagram.

Teahead, since you have a 2800cs, here are the wiring diagrams from the blue books in PDF for a 2800cs. the signal system is on page 4, but the power side to the lights is on page 1

blue books are the best have them blow up to 24 x 36

I used these two. Might not be the right year - it wasn't for mine but I muddled through. The black and white one was most useful - once loaded on ipad for ease of reference.

Isn't 43 and 44 for the HAZARD switch/relay? Those are separate from the turn signal switch/relay, right?

I must be blind, but I can't see where the turn signal relay/flasher is?

Hazard relay is also the turn signal relay.
