Bee*R Rev Limiter to 1ZZ-Fe connection problem


Fresh Recruit
Hi i need help with connection bee*r to my 1zz-fe ecu. I have problem with get the rpm signal.
I tried connect it to TACH on ecu and IGF but with no results.

I connect:
Red wire to 12V battery positive
Black to battery negative
Green to NE+
Yellow to TACH and next to IGF but device don't read the signal :confused: if i swap wires engine dont start.

Of course the Bee*R is the original one, 30th anniversary with switches
