Re: Installing a SpeedHut tach... where on earth do I plug the power lines in?

Amazon... I'm almost ashamed to admit. But they work great from what I can tell! I might look into amber LEDs to match the tach... but not today.

No clock. BUT... I found the factory plug! It was hiding (and I finally found another image on ratsun). Apologies for the blurry pic... now I need to find a compatible connector to do this properly.

Re: Installing a SpeedHut tach... where on earth do I plug the power lines in?

There is power for the optional clock tucked in the harness wrapped in blue tape. It's up in the dash cage just above where the tach would go. I'm assuming its constant power.. and there should be switched power for the radio. It's a blue wire. This "harness" term seems like a vague descr...

Re: Installing a SpeedHut tach... where on earth do I plug the power lines in?

I bought a multimeter (had one years ago... no idea where I lost it). Figure it'll come in handy for this.

Re: Installing a SpeedHut tach... where on earth do I plug the power lines in?

I believe thats cause the needle is always on, where as the gauge lights is only when the lights are on - you could probably simplify it and run them both to the same power source but then the gauge would always be lit up. This diagram may help. I used it a lot for reference whe redoing my wiring a...

Re: Installing a SpeedHut tach... where on earth do I plug the power lines in?

Connect the +12v power supply to the light for it as well. You can't see it in the daytime and it's on when you want it. The needle? The wiring is pretty interesting on this tach... the needle light is separate than the gauge light. But... where? How? There's tons of wires behind the scenes, but th...

Installing a SpeedHut tach... where on earth do I plug the power lines in?

I finally got tired of not having a tach, and waiting for an OEM tach at anything near a reasonable price seemed impossible... I ordered a SpeedHut 3 3/8 tach. I've got it mounted after some cutting and drilling in the old idiot light cluster. But... now I have to wire the thing up. The tach signal ...

Re: R180 diff? Something seemed off and the car's geared really short... best avenue to fix?

I could always try to find a 5 speed with a lower ratio than I currently have... it's making noise when in gear and probably needs a rebuild at the least...

Tach comes tomorrow, but I won't be able to install it for a while (this atmospheric river thing puts a little rain on my parade).

Nice! That's probably the easiest thing, right? Find a new lower ratio diff and swap it in, then sell this one? Better than trying to regear?

Re: R180 diff? Something seemed off and the car's geared really short... best avenue to fix?

Thanks all... my son and I jacked one wheel off the ground and spun it six times - the driveshaft spun a bit more than 12 times - per his calculations this means it's a 4.11 ratio diff. This certainly explains a bunch of things! Now... time for a 3.9 or something. 4.11 is too high for my tastes, I b...

Previous owner was an... interesting... fellow. He fetched quite a few parts from other junkyard datsuns... L18 (from a truck?), 280zx five speed, and now the rear diff... so bizarre. This car has been fun to work on (for many reasons!). Who knows what else I haven't found yet that's different.

Sorry that's a horrid pic of mine. I aligned the crank pulley to zero and the notch was perfectly to the right at the crankshaft. I made a wooden block to secure the chain but didn't end up using it.

Re: R180 diff? Something seemed off and the car's geared really short... best avenue to fix?

Also... unrelated... but here's the camshaft. It's on the 2 position (engine is not at TDC, for the record). From reading the manuals and various references online, it seems like it's in a good spot, although I probably need to either replace the chain or adjust the guide(s). https://i.imgur.com/RbX...
