New Tach for the V8 (1 Viewer)

[exrsa1]

I've been wanting to replace the Tach in my 60 since the OEM tach is not calibrated correctly for the V8 and I did not want to do the Potentiometer. I have been looking at all the Autometer gauges, since I will be adding a tranny temp gauge in when i do the 700r4 next week as well.

I had however read somewhere that a Sunpro 2 5/8 fit real nice with some funky bracketry in the stock location, replaing the old oem pod completely. I happened to be in a auto parts store today and they had a Sunpro in stock Part #CP7906.

I had a spare dash from a 60 and started working on making it fit, and just did not like how it sat in the location. It was too far back. I decided to take it apart and see if I could make it fit in the original pod that housed the OEM tach.

I was in luck, the holes lined up for the screws, some slight trimming of a tab in the bottom of the pod, and an extra hole drilled for wires, and even the original lighting will work.

Once I had it installed in the dash, I plugged it in and basically fried it......:whoops: I had incorrectly assumed the stock wiring will match up. I should have checked the wiring before I just assumed.


SO, a real nice install, and once I get the new one, I will finish the wiring and have a working Tach.

LOL yeah, did I meter the wires? Meter? me? LOL! As I have said many times before, electrical is not my forte.

Thank goodness it was only a $25 gauge. I was pretty darn pleased with myself till I did that. I should have just run the red to fusebox, black to ground and the green to the plug at the coil, instead of what I did. Oh yeah, and it would not start with it plugged in to the harness. Probably grounded it out somehow.

Nice job on that - somewhere in my build thread is info on using the stock stuff and having it rebuilt to work with the GM V8, also I had my faceplate re-printed with a new redline as well.

Your solution looks faster/easier

Yep, I had read yours and also spoke with Iaintscared and if not for the cost, would have gone that way.

Done

Installed the new tach tonight. I actually metered the wires from the plug this time, and figured out I was way off on my assumptions. All good now, and the tach works great. The lighting is too bright, and I will have to address that by moving the tach inside the pod closer to the window.

All in all a 1 job.

Looks awesome. Very nice job.

Wish I would have known about this instead of spending big $$ for Redline to calibrate mine-- which has not worked yet. Problem on mine seems to be the computer is not sending the proper signal...
