Hi,
I don't have a harness for this unit, so I must wire it myself. I found a nice write-up about wiring particular sensors etc, so that's not a problem. But SFC must be grounded somehow. Could anyone explain how should I do that?
TIA

i grounded mines and my friends to the ground on the ecu.....where the screw that bolts the ecu to the car.

...and which pin in the rear plug did you connect to?

 

I had one in my last teg and just followed the instructions on temple of vtec and spliced into the ECus ground wire, worked fine for a year then i pulled it out when i sold the car.

 

I still don't know to which pin in the plug I should connect the ground
But thank for your replies.

 

OBD1 or 2?

remember a ground is a ground i know a few people who groung to the block

 

best ground is either on the chais or engine block but again a ground is a ground

 

But VAFC is supposed to be grounded to the same ground as ECU, that's why I'm confused. What is more it must be grounded with two wires and one of them must be closer ECU than another one. Damn, I'm lost.

 

well the ECU is ground on the engine where the thermostat is, it connects to the bottle neck part of it. the other ground I'd say would be chasis
