I hope to make this a Sticky (Mike!!) I want to Document every S30 style combo and Turn Signal Switch. I need every one to see what is already posted and add to this Thread if you don't see your style of switches. With any luck, anyone can pick up a switch out of a box of parts and be able to cross reference it here and know exactly what they have. I am now in possesion of over 80+ switches that I would like to start rebuilding for people and customers. Only problem is that there are so many styles that I am not totally sure of what is what. So PLEASE remove 4 screws from the steering column cover, take off the top and bottom covers and......... Take a picture of....…

My brake light is on and I’ve disconnected the parking brake switch. Based on the service manual the proportioning valve switch must be on but I can’t for the life of me see an electrical connection to it. What am I missing here? It’s the valve on the firewall with the four hard brake lines right? Driving me nuts!

All guages were working before I made the switch to a megasquirt fi system. I found that the tach wire (blue) was shorting the ignition system out when it was attached so to get it turned I just left it off. When the engine is running it will short out the ignition if I attach it and the engine dies. I thought it might be the tach so I pulled the guage and wire plug out of the dash completely and the engine still dies if I try to attach the ble blue wire while it is running so I don't believe that the tach is the fault. Looking at the schematic in the service manual it appears that the blue wire goes to a resistor but I don't know where that may be, anyone know? I h…

Does anyone know of a more detailed wiring diagram for the blower fan and switch? I found this one but it's too basic, there are 6 wires coming from the switch and I need to trace them down. The car previously had A/C and I think the wiring harness has been modified. ColorWiring240Z-1971-USA-Early.pdf

The signals are doing some strange things that make no sense to me, using the old flasher unit, sometimes I can get all four signals to flash by moving the signal stalk left and right. Then the next time I go back to the left the front left signal won't flash or light up, the rear left and right signals always work no matter what, switch back to the right and now the front right signal doesn't work. Then a couple more tries and they all work again until the next time and the front left stops working. No rhyme or reason, I have taken the signal switch apart and cleaned the contacts with a scotch pad, the signal bulbs are working fine, I've switched them around, I've j…

I'm putting together an order from Eastern Beaver for some electrical terminals bits and pieces. Anyone interested in tagging along and putting stuff in on the order? I'll send you your parts once the order arrives on-shore. Domestic shipping should be cheaper than the shipping from Japan. Their shipping isn't fast, but some of the stuff they have is really hard to find elsewhere. https://easternbeaver.com/Main/Main.html Some examples:

There are three of them, one on the distributor, one on the coil and one near the alternator. There is a new alternator coming with an internal regulator, the spark is going to be handled by a Pertronix II unit and the spark plugs are NGK BPR6ES, do I need them? Thanks

Just noticed the high speed position on the wiper Combo switch is no longer working. Should i just dump that old and tired wiper motor or could it be something else?

Who here knows the proper title given to the circuit board that s30 ZCAR headlight and turn signal switches use in their switches? This would be someone with a command of ZCAR esoterica and sadly, most of those guys are passing on. I miss them.

Hey gang, So it's time for a new battery - my Interstate MT-24 from 2018 has thrown in the towel. Should I just get another one of those or is there a commonly agreed upon better one to go with, without breaking the bank?
