Hilux v6 conversion Tacho wiring

[Nicke123]

I’ve dropped in 2000 VT commodore v6 3.8L ecotec motor. Into a 1996 Hilux solid axle which had the 22r 2.4L petrol motor. I bought marks 4wd wiring harness. But does not include tacho kit. I have a saas tacho gauge I can use if I can’t use genuine. 

 

Just wondering if it is possible to wire up or do I need to buy marks 4wd tacho kit for it to work? 

 

If so where do I tap into the signal wire? 

And do I need to use a special negative or can I use any negative?

Can someone please help me. Thanks

I can't help with finding the wire but 

Most Toyota tachos from that era use a high level input. Thay means they need a voltage spike off the negative of a coil to work. 

I had a quick search and it seems the Holden motor is a high level signal too so you might just need a tacho from a 6 cylinder Toyota and to find the right wire in the Holden wiring loom, assuming you are not running after market ecu and wiring
