80 diesel tacho wiring?

[rusty82]

got a poverty pack 80 series with no rev tacho or oil presure gauge, ive bought after market gauges and can any one tell me where to pick up the signal from for both in a 92 model 1hz

i think the tacho can come off the alternator w output. I was looking into a vdo tacho for my 60 series and that's where i was going to do it.

I think i remember reading another post about this a while back??

From memory the only other way (apart from alternator) is to get a GXL fuel pump that has a specific tacho output. (I got quoted around $800 to change over mine!! )

Having said all this, I'm going to try another route!
As I understand, tachos normally run off a negative pulsed signal (usually off a dizy in a petrol), so I'm going to try an NPN proxy switch running off a stepped disc mounted on a fanbelt pulley.

I've got all the parts, just got to mount them
(After I refit the box, t-case, pto, clutch, and both diffs )

anyways, I'll let ya know how I go

I'm also interested in the oil pressure gauge.
(I've got the same - '92 pov pack 1HZ)
