Why do you wanna use the external tach and temp gauge?
Just remove your cluster and jump the resistor and have a working cluster.

I have a sc400 cluster and jumping the resistor didnt do anything, grounding the brown and black wire didnt help either. ..

I have to tackle the RPM gauge as well. When I first did the swap and didn't feel like removing cluster I bought a cheap Temp gauge at auto zone and stuck the temp probe up the nipple on the water pump no longer used for the twins feed.

But heres a link to some useful info for ya https://www.clublexus.com/forums/per...-tach-fix.html

What color is that nipple thing on the water neck, is it green that suppose to be attached to a senosr, I couldnt find it actually.
Yea That link only works for sc300 clusters not 400 custers. .
