stock tach sender is in the bellhousing for bj's, but autometer sells a diesel tach that has a probe that straps to the alternator, so would work with pretty much anything.

is there a way to hook up my stock tach to any of these units?
I would like to keep things as simple as possible, and avoid cluttering things up with more gauges?

Im a bit the same way with gauges and I dont like drilling holes in the dash
I think the easiest way for you would be to source a HJ60 tach and run a sensor off the flywheel like the 2H diesel does. Im not exactly sure how you would connect it.
Otherwise there are pulse tachos that detect a pulse from the fuel injection line and covert it to rpm.

I know of some little box made by dakota digital and it is supposted to take a diesel pick up signal and make it into a signal a gas tach will accept. I think it can be calibrated for various things, like how many cyl the origional tach was set up for.

well, somewhere on this board, there were a few pics of someone who put this guage into the stock hole on a 60, so there was no extra clutter or anything ..

I would be willing to substitute the stock gauge for an aftermarket one. But I would not un der any circumstance leave my dead tach in the dash and then mount a 2nd working one. Just a half ass way to do things.
I mounted #2888 in the stock location on my HJ60. I used the factory screws, no additonal drilling required.

I could like with that. Looks like it has been there since it rolled off the assembly line.
What is better out of the two different kinds of diesel tachs. Ones that draw their signal off the flywheel or off the alt.?

that seems like it would be the easy way to do it. I would like to try an isuzu diesel swap, in conjunction with a frame off restoration. That was much of the placement/fab can be done with a miniminal amt. of stuff in the way. Has anyone done a isuzu swap yeat?
12v tach
I used VTs thread to find my tach, the same one discussed here...it's a 12volt tach, it uses a small induction pickup from the alternator, and a 12v power wire and ground. I run mine off my 12/24v converter in the truck for the cd player, works great, installed in under an hour. I put a backing plate in my steering column and hung it there, works perfect.

VT,
That tach. looks great. I will have to make a note of this for when I get this far.
I know your truck was a HJ. Will this tach fit in a FJ60 dash the same way? My 1HZ is a 12volt. Will that make a differance?
Frank
Yes, i believe mounting it should work the same for and FJ.
easy, just a few screws to remove the cluster, and then just unclip the wiring and disconnect the speedo cable. It can be tight trying to reach some connectors but its not bad. tilt the steering wheel as far down ot of the way as well.

I herd on the fourms some where that you can just pull the cover off the steering wheel. Is this really the case? There was talk to fixing a squeeky steering wheel. Basically just lube it and reassemble, but I dont want to go yanking on anything yeat, until I know for shure.
