My truck is has no tach... I liike tachs. I was thinking about heading to a junk yard and grabbing a instrument cluster out of another truck that has a tach... but does I assume that I would have to run wire to hook it up? anyone done this? or should I just keep my old inst cluster and add an after market gage? Im torn, anyone have an opinions on the matter?

Thanks!

It can be done. I put a cluster out of a 95 bronco in my 92 f150. The wiring was different and some things didn't work, but i took both clusters, layed then side by side, and mapped out which wires were for what, and just changed thier location on the truck side of the harness.

I'm assuming if the years are the same you'll be all set, but because mine were different, I'm unsure.

I put an aftermarket tachometer in my truck. Seriously, nothing I have ever done in my life has ever been more of a pain in the ***... my dad had to do most of it and he's a mechanic and was struggling to do it.

Good old Bill

Am sure the up to date guys will chime in. Here is my two cents from years past. Hand held tachs had two connections, ground and the negative side of the coils primary circuit. Would think todays aftermarket tachs would be just as easy. Personally, I would like the original cluster to incorporate the tach, old school was a tach, oil pressure, and water temp. It, deffinately cane be done.

Putting in an after market tach is gravy, its only 3 or 4 wires....

ground right under your dash
power right under your dash
switched power (for light) optional headlight switch-dash
signal (negative side of the coil) in the engine bay

I'm actually putting an aftermarket tach in my truck. Luckily you don't have to run the signal wire all the way to the coil, you can just splice into the wire for the oem tach in the harness for the instrument cluster.

The wire for the tach should already be there, just install the donor cluster that has the tach.

I just did a write-up of installing a tach on my 96 302 truck.

Pictures included. Check it out. Hope it helps
