You're the 2nd guy to ask this week. But I can't help you. Not this second anyway- going to bed. I did this ground last summer but I didn't bookmark the FAQ where I got it from and I don't have the hardcopy anymore...

I will look tomorrow (hoping to spend the afternoon working on other things and it won't be a problem to pull up the carpet for 2 secs.)

If ya gotta know NOW, poke around in the FAQs. That's where I found it. Otherwise, hopefully I'll have a post for you Monday night (Tuesday at the latest - promise. )

And I haven't done the injector ground. But I am going to try installing a capacitor next month to see if it will eliminate the 3800 stumble (and to make life easier for the charging system in general.) Search the forum for "farad" and you should find a recent thread about this...

ttyl,

I dunno what you mean by "grounding the injectors" as they're fed constant 12V and the earth is switched by the ECU, but here's a link on regrounding the ECU.

While your grounding things in that area, add an extra ground to pin 2C on the ECU. Pin 2C is the ground for the tps, boost sensor, variable resistor, water thermo sensor, atmospheric sensor, afm sensor, etc. Can't hurt to do it. Takes but a moment to do so. Then go to the small plug and ground 3A and 3G as mentioned in the url NZ CONVERTIBLE mentioned.
