hey guys
i have a 1994 hzj80 1hz budget edtion series cruiser and was wondering if u could put a gxl dash cluster in it to get the tacho? is the wiring already there?

thanks
matt

there is lots of tech on this, do a search, its been covered off a couple of times.

good luck

the short, short version:

you need the oil pressure sender + install to engine.

you need to r&r the injection pump, disassemble, drill and tap, and install the tach sensor. (or get a pump off a 75 or 80 with a tach).

you need to either install the overhead console or some trick wiring and a switch so you can get a level on both fuel tanks.

you need to get the right instrument cluster, there are 3?? versions depending on year of manufacture.

liek rob said, search, there is a ton of tech on this. to get the tacho to work, you have to be pretty determined.

the good news is, all the wiring is there already.

As you probably see during your searches, it is possible to tap into the alternator to get a tacho reading.

I have done this with my own 80 series (also a poverty pack) and have a 2" tacho and oil pressure gauge sitting on the front side pillar.

I haven't confirmed the tacho is 100% accurate, but it's definately within ball-park (tells me I'm doing about 2200 - 2300 revs at 100Km with 285 tyres)

thanks for the info guys much appreciated!! im not that determained to get the tacho to work but as ill be having gas injection fitted in the next few weeks now ive got the turbo up and going i went and spoke to the gas guy and he said as "landcruiser tom" said and he drags a tacho pulse off the alternator on one of the three phases so ill get in and do it that way
thanks

Tom can you elaborate on how to actually do this. eg what wires where etc. I've searched through I don't know how many threads but all I can find is discussions on getting the signal from the alternator but not one about how to do it.

Wondering if it could be a cheap fix to get the factory tacho back in my 1HDT 80 with a 1hdfte conversion.

Can't find anyone locally who has any knowledge of getting tacho working from ECU and those far far away who have done it won't share any info. That might be understandable but frustrating when I'm never in the market to get or not get a conversion off them but definately in the market to get an adaptor or such to get tacho going.

So maybe alternator is next best option.

My taco runs off the back of teh alternator as well.
I'll have a look for you when I get home tomorrow and post some pics.

If your down Brissy way pm me and we can organise a meetup adn you can check it out yourself if you want.

yer that would be good hey as id like to know which pin you pulled the signal off as i need one anyway for my gas injection

Yeah pics would be great. Do get to Brissy on occassion but not sure when next otherwise pics will hopefully be enough. Not even sure if alt will get reasonable trigger to factory tach anyway but it's a start.

Id be interested to hear how your Gas injection goes.. I was contemplating doing it to my 1HZ with Denco turbo. Place at the sunchine coast does em for $2,900 then I get $2000 cash back from that so for $900 out of pocket expenses its looking attractive.

I did a dash cluster swap too but got the fuel pump rebuilt and they changed the housing over to one with the tacho sender in it so was all sweet for me. Still got to get around to hooking up a switch so I can get a fuel reading on both tanks as I didn't go with the roof mounted sub gauge.

wow is that fitted cause that sounds like a deisel gas vapour system??? the deisel gas australia computor controlled injeted system is more than that hey!!! mate who's a gas fitter just did the system to a land rover and it cost close to 5000 i think
