Hey all, just thought I'd share my days work. Today I completely refurbed the guage carrier, and installed and wired my new tic toc tach.

The carrier got 2 coats of "repro" semi-gloss laquer, after cleaning with acryliclean 330 twice, wetsanding, and cleaning again. Then I stuck on my new repro chrome trim rings. Hope they stay stuck.

Had to drill the new lens for the clock adjuster. I installed it all, put a peice of tape on the lens, dabed some paint on the clock adjust rod, and carefully put the tach in place. Then I drilled the paint mark on the tape. Worked perfect.


So far so good, on to the back. I started with a speedo with a temp and oil light, and a fuel guage with a gen and brake light. Now I gotta tach with no lights. For $140 I coulda bought a circuit board with wiring for a brake and low fuel in the speedo, but no where am I finding a lens for low fuel. I'm using auto meter console guages, no low fuel, no ammeter and want to keep all 4 original idiot lights anyway, so... I modified the original circuit board. I'll use the former fuel level wire for bat pwr to the clock, the existing ign. wire to power the tach, and soldered some leads on for the 2 lil light I got at radio shack to replace the missing brake and gen lights. I also had to bring a ground over for the left turn signal. The only change in the dash harness will be to cut the fuel level wire, and run one end to the console and the other to the lighter curcuit. A separate wire will go from the tach to the coil.

very sweet!

Big fan of tic toc tac, and nice job with the LEDs

The AM console gauges are a nice alternative to those expensive (and unreliable?) sawtooth gauges.

Looks like things are coming together nicely

Figured I'd put this pic here, so as not to start another post. Friday night, the consolde got cleaned real good with acryliclean 330 (I'm really liking this stuff, it's a good thing I have no idea how much that gallon cost me, it will clean ANYTHING!.) Then 2 coats of oer semi-gloss black laquer, and put back together with the new a/m guages. I stripped the woodgrain thing off the gearshift surround, found nice shiny chrome under it, and decided to keep it that way.

Re: TicToc tach retrofit

Jim,

Do you still have all that info written down somewhere for this install?

I'll be tackling the same thing this weekend. I already have the console guages and will add the tic-toc-tac.

Re: TicToc tach retrofit

I'll hafta dog for it, but yes. Give me a day or 2 to find it.
Are you using factory guages or autometers?
did you get the tach pcb or will you modify the old one?

Re: TicToc tach retrofit

Jim,

I have the same gauges as you (Autometer) and am installing an OER tac just like you did.

I bought the PCB for gauges ($50) but am considering doing what you did and modifying the original non-tac PCB to retain the idiot lights....

You may need more than that small bulb or LED for the GEN light. The alternator uses the resistance of the bulb to excite the field. You might want to put a bulb similar to the old one in parallel hidden somewhere.

Re: TicToc tach retrofit

The main reason I used the existing circuit board is I wanted to maintain function of all the idiot lights. As I'm sure you can see, the tic toc tach doesn't have any, only a turn indicator.

With a 68 with factory guages, the brake light stays where it is, the oil light becomes a low fuel, (I tried, but never found a low fuel light lens) and the rest go bye bye.

If you look at the dash connector close, the pins are numbered.

Pin 1, Tan wire, fuel gauge. Cut it, extend harness wire to console fuel gauge
Pin 2, Dark Green, Temp Light. I extended this to one of the small lights I added.
Pin 3 (6, no connection on 6) Illumination, no change.
Pin 7, Pink, ignition switched power, this needs to get to the lower right terminal on the tictoc (looking at the back) If you keep the gen light, needs to go there too.)
Pin 8, dark blue, turn indicator
Pin 9, light blue, turn indicator
Pin 10, Tan, brake light
Pin 11, Brown,
Pin 12,

Please ignore this for now, I'll get back on it tomorrow
