USC 131 Crown speedo signal wire

[truck builder]

Hello guys i need a hand with some wiring issues

i am having difficulties getting my electronic speedo to work in my 90' Hilux with the 1UZ, it has no signal

I need to know which is the signal wire from the ECU that i connect to the hilux speedo cluster?

If any one can shed some light it would be appreciated.

signal comes from the speedo sensor on the auto box up to the dash

then the signal goes form the dash to the ecu which is not imnportant

so find the 3 wire speedo sensor on auto

one wire is 12v one is earth one is signal


then the signal wire goes to the hilux speedo which i think is green/red or green/blue

the wire that goes from the dash to the ecu is not there on a hilux cause a hilux that age was carby

so with mine i got a dash plug wire from another hilux and plugged ti to correct spot and then ran it to spd wire on ecu
