Were can I get a cheap tach for my truck. It didnt come with one from the factory. Also were have you guys mounted them? Any luck on finding the tach wire in the harness?

 

Cheapest way to get a tach is to find somone wrecking a similar truck with a tach in the dash.
Swap it in and there you go.

 

I got mine for nothin', a guy I know didn't know how to hook it up and thought it was broke so he gave it to me. I know it's only worth $40-50 or so new. Don't know where to get one cheap off-hand.

It's an Equus 6086 Pro Tach.



No way to hook it up (that I know of) without running a wire out to the ingintor(-) neg terminal. There's a hookup for a tachometer next to the fuse box and the diagnosis connections in the engine compartment, it's marked IG-. I spliced mine in to that wire where it starts, at that green plug deal there.

 

I love the amount of mud in the truck cab

 

She's my muddy little piggy. She's never happy when she's "too" clean.

I do wash 'er up a couple times a year, just haven't this year yet.

 

well if you can find one, i would try to get a dash with a tach from a junkyard

 

Looks like my cab the majority of the year hahaha

its clean now tho, i guess the final emersion of sun inspired me to clean 'er

 

This is sorta related....: so what's the red-line for a 22R anyways?

 

I have a 5 inch monster tach with shift light on the left side of my stock cluster in the corner, Wiring is easy! Theres a plug that comes off the coil, thats the feed for a tach. I'll get a picture of mine if you want. I like how it looks, I didnt want so big but I had it in my Camaro and after installed it looks bad-a$$ in a lifted yota...

Also check ebay for tachs, I got a used monster tach off there a couple years ago for like $20

 

Where do you tap into actual power?

I have been running it straight off my battery (jerry rigged, i know i know, i have learned my lesson...) and had nothing but issues with that. This caused a drain in my system.

I just had to replace my alternator so i am wondering if i had it wired correctly and my poor old alternator was just not cutting it.

 

You can use the same power wire from your sterio, or jsut hook it up to the fuse box, get a test light and test the wire to make sure its only hot when its running or accessory position

 

take the glove box off, the lower dash, and center console interior pieces. Where the clock would be, the wriing is still there. itll probably curled up in the back with a plug on it, use the red for power, black for ground(or to the body), and the green clock wire for your illumination on the tach. the green will need to go into the ignitor coil.

 

usually you can take the radio bezel off and find those wires, i did at least. also under my speedo cover there are wires for a switch that are hot.

But being a electrical person ill do my own fuse after the battery lights from the oem sterio hook up or gauge cluster and jsut ground it off

 

What trim should I be looking at the junk when trying to find a oem tach in the 84-88 trucks?

 

I have a Sun-Pro tach from Autozone, I think it was 29$ (?) Works really well and is made by Snap-on

 

 

Thats the one!

 

SR5. It's called an SR5 gauge cluster/combination meter swap.

I mounted mine on my 87 on the right hand side of the instrument cluster. Drilled two small holes and ran the wires in another hole I drilled under the tach. You can barely see the wires. Sorry no pics.

All you need to do is wire the tach up how you demonstrated and it will work or do you need to install something else. I don't really understand how the tach would get a reading of the rpms with just power running to it. My 86 pickup didn't come with one stock and I'm really trying to figure out what I need to install one.
