Am I Missing "passing Relays"

[aircobra]

just working on more wiring and looking at the FSM (BE section), it shows a pair of "passing relays" in line just after the light switch. all the threads say that the headlights are wired directly from the switch, so the wiring goes from the switch to the fusebox.

is this a year-specific mod that appeared in the later cars eg '72 on?

i'm looking at the FSM that says "S30" on the cover
 

[aircobra]

did bit more digging . different versions of the S30 manual show

 

Out of standard manual

1. standard - 2 Passing relays

2. US and CANADA - NO passing relays

 

Out of the "supplement"

1. EARLY basic version for US - one relay

2. LATE basic version for us - NO passing relays

All shows "ACC" relay - in between the defroster switch and the glass. This must be under the dashboard somewhere

Not clear on the logic here at all  - sounds like there are variations on the years and the geographies

is the logic that some countries use their headlights more than other?

Different rules regarding lights required in different countries ??

 

Just a guess.

Can't comment on earlier cars but my 9/72 has 2 passing relays. The button is on the end of the indicator stalk.

1 relay is on the passenger kick panel the other is on the drivers kick panel.

I always thought the pass button on the stalk was a 260Z thing. My 7/73 model doesn't have it.

ok, the colors match. i think this is the twin passing relay circuit - the colors match. since my relays are missing, i'll have to use the generic 4 post black ones

[aircobra]

not sure, maybe someone swapped it over. however if you look at the circuit, there's definitely there for some versions. i'm not sure why there's 2 of them - one for each side? someone must know this

Can't see your pics on my phone. Maybe post direct to this site not to a photo bucket type site.

 

They are 4 wires so yes simple 4 terminal relays.

 

It's been about 5 years since I liked at the wiring diagram and that circuit but from memory the reason there is 2 relays is that 1 relay supplies power, the other supplies the earth.

ps. the horn relay has a couple of labels on S, B and H by the looks of it. which wire goes to what terminal? doesn't say anythingm in the fsm

Google says;

S = switch

B = battery

H = horn

bought a couple of $5 Jaycar relays . see if they do the trick

[aircobra]

al good, except that now i have double relays, 4 all together to be exact.

i'm sure this has been covered before, but i don't understand the wisdom of having relays ONLY for flashing high beams and not for the headlights

anyway, i have these 2 factory replacements and the standard ebay chinese $10  H4 loom.for the main circuit sitting at the front of the car. so basically its double relayed and it all seems to work

the only exception is the small button on the tip of the indicator stalk - which is some sort of a "flash"

anyway, to get the whole thing going, i need to juggle the twist control, the flash button and the high beam switch ( pull on the indicator)
