Ok i just swaped out my digital gauges, every thing worked before, after swaping in the analogs, Now the boost and speedo don't work? Whats wierder is that the water tempeture gauge works, and i haven't changed the sender up front on the engine, so whats the deal. Do i need to splice in some wire from the digital gauges or what, any help is needed? Also my odometer and the milage clocks aren't working.

Ok thanks for the help y'all, i figured out the speedometer, but how do i fix my boost gauge, can i straight wire it to the block or what, Help. Please.

Boost gauge gets it's signal from the boost sensor... you can also adjust the trim w/ the adjustor by the glove box.

What? i got a n/a dash harness, on my turbo what all, do i do to get it workn.

NismoPick

That does explain a lot Do you have the boost sensor? Bleach kept his na dash I believe... might want to see what he did <Bleach is summoned>

wreckedj30

yes? i just swaped in an anolog gauges, i used the wiring harness and gauges from the n/a, i still have the digi, harness and gauges. The analog harness was in n/a. Digital was original, a turbo. K, so what wires do i need to pull from the digital? And can i straight wire it unstead or do i have to splice fuse blocks. Cause i really don't want to do that.

So bleach, is to stuck up to help a fellow zdriver, thats wrong. JK but seriously i need help with this, i fixed everything else, but the boost gauge. How hard is it to set an aftermarket one up, or just fix this one. Help y'all.

NismoPick

You didn't answer my question.... do you have the boost sensor hooked up? It's bolted to the front of the left strut tower on the turbo models.

wreckedj30

Yeah i didn't remove any thing else. I had it all working, then i swaped out my dash to analog, and it had less wires, so it no worky now.

Bleach

I'm running all NA analog gauges. I have an Autometer boost gauge with a vacuum line run to the manifold.

So when I swapped the turbo engine into my NA car, I basically left the dash and gauges alone that were there. I like the voltmeter and the big oil pressure gauge that the NA has.

wreckedj30

Ok so if i get an after market gauge, all i'll have to do is run a vacuum line to the manifold, no electricity. Cool, and what took you so long? Also whats in the third dash hole.

NismoPick

That's usually what people do anyway... an aftermarket gauge is more acurate. I've got my stocker & a pillar boost gauge.

Which 3rd hole ya mean? The left or right one?

wreckedj30

Thats a purdy dash nismo (now i like it red), no bleach said that he likes the big oil pressue and the volt gauge, i was wondering whats in the third hole, oil temp. or what?

NismoPick

That's why I posted the above pic

From left to right:

-Oil pressure gauge (turbo model has oil temp on top, smaller oil pressure below).

-Voltmeter on the NA... Boost gauge on the turbo.

-Clock... all digital, except for the base model 79/80 had the analog clock.

wreckedj30

Oh, see what i thought is they deleted the volt for the boost on n/a's and had something else, i'm lagging to day, anyways, i'm just going get a new boost gauge and hook it up, so when i find that, i'll repost. And do i need anything(wires, etc.) for the 120mph speedo, or will it just hook up. Sorry for all the questions, its because im a lame. But at least i drive a z, huh.

Bleach

I didn't check Zdriver for a few hours yesturday, oh no!
I was working on my Pulsar and a friend's Z.

The 120 speedo, should just hook up. It worked in my n/a's, just did a instrument cluster swap. Of course I didn't have digital, nor a Turbo. So I don't know what the difference is, between them if any. But I really don't see why it wouldn't work.

wreckedj30

Ok, yeah now i have the n/a harness so it should work, i'm just going to swap in the whole 79' dash since they had the 120mph speedometer. Right? There the same price at the yard, but the guy said there different, so whatever. I'm gonna go get it on pay day. . Another question, does your gas gauge, analog, go to empty, then the bottom 1/4 to none work or what. Cause i'm gettin scared.
