Cheers '93!
Maybe I need to preface all of my posts with "I've got an MX5 with 1990 stamped on the VIN plate, the parts appear to be whatever fit and were available when they needed replacing last"
White/Red from the back of the indicator stalk is indeed the high-beam signal, regardless of if it's a click-forward, pull back, or "randomly turning on" (Checked by testing against white/black with the MM, which is almost a clean earth, 130 ohms to the door sil)
Wiring diagram is here (1994 version, not the 1990, but the '94 version has no white/blk wire listed, and the 1990 version is missing that whole section)
https://s3.amazonaws.com/miata/miata/19 ... agrams.pdfThe Lights dont pop up if they're down, but they do go high beam - if i have the lows on, the highs will turn on as well as the lows when it's in it's fault state which made me think there might have been two "sends" from the indicator stalk, however, this does not appear to be the case, the low beams turning off when the highs come on appears to be a function of the switch.
I inspected the mechanism of the switch while I was poking around, the whole lot is rather sloppy in every direction, so I think it's time to just get a replacement stalk, foiling my attempts to be a stingy bastard.
