Speed sensor - HELP

b16a4me · 21st March 2002, 01:54 AM

I've just got my car on the road after a B16a implant.

I've got no VTEC. :cry:

The computer from a 1991 teg needs a signal from a speed sensor (which

my car doesn't have).

I have the speedo head from the front cut and I pulled it apart to find two

terminals, one leads to the computer and the other ???. I need to know

whether the speedo grounds a signal from the computer OR if the speedo

sensor sends a signal to the computer from a power source.

If I had a wiring diagram from the donor car I could figure it out but I

don't. :cry:

Can one of you VERY KNOWLEDGABLE kiwis possibly help a fellow Honda

addict out?

Thanx in anticipation

check the hondata site for a pin plot of the ecu, 2 PIN??? Ive only seen three pin ones, which are a sort of three phase altenator.
