Greetings Humans!

Does anyone know if the flash-to-pass and high beam are the same wire coming from the indicator stalk?

If not, do you know which is the flash-to-pass wire? I've had a look-see around the intertubes and I'm unable to find it.

Reason being my indicator stalk is dicky and high-beaming people randomly, and replacement parts aren't in the budget for a little while, so If i can snip the wire in question I can solve my issue, and only lose a feature I don't actually use anyway. (If I'm annoyed enough to be high-beaming someone, they're not getting courteous little flashes )

Flash to pass wasn't factory on the 1990 ADM NA6, so yours has been modified, or may be it's JDM & they had it from the factory.

Anyhow, the flash to pass mod page should help:

This is GOLD.

Cheers Clubman, I was only thinking about this last week when I discovered you can push the wiper stalk forward and get one pass of the wipers with out washers.
I never thought it would be that simple to sort out this little wiring gremlin.

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)

The 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.

Mentioned the ADM 1990 didn't have flash to pass as it might have been a shortcut fix, ie remove mod. But unfortunately, as you've found, this issue tends to result from wear, which causes sloppiness, which causes shorting.
