hey folks - i'm just about to start on the next step of making my car 'faster', but i'm unsure as to how i might achieve the step listed below

-----------------------------------------------------

2. Now, to disconnect the connector #4 and to find a means of connecting the selenoid which is below of this connector #4 on the same wire as the connector #3 (fuel cut-off selenoid). You can let the connector #4 hang, it is now useless.

This modification prevents the pump from "delaying" the timing to reduce the Nox (polution) It is necessary that this selenoid(#4) is activated (12v) with each time the engine is ignited to keep the advanced timing even with low RPM.

---------------------------------------------

how might i be able to connect the selenoid to connector #3?
anyone done this that could shed some light?

many thanks!

you would remove #4 connector, then take another piece of wire with a similar end and splice it into the #3 line somewhere, and run the new wire over to where #4 would go...

Is the solenoid in the red circle pictured here the one that needs to have a constant 12v feed to it? And this solenoid is a timing advance of some sort?

I dont think this solenoid works on my car and I've had a hell of a time starting it when warm, but if I advance the timing with the cold start lever it works great. What does it get its feed from? A temperature sender?

could i snip #4, splice it to #3, cap the leftover #4 wires?

Why dont you just leave enough wire of the #4 connector, cut it, put a round connector on it and hook it to the fuel solenoid on the pump?

no the solenoid in the picture is not the one tha tneeds a constant 12v, the one that needs a constant 12v is the one under the lda, it looks almost like a oil pressure or water temp sending unit or something

The solenoid your referring to would be the fuel shutoff solenoid and that has 12v anyways, because if it didn't, your car wouldn't be running. #4 in the picture posted above I believe is what I have circled in mine, and that article is saying #4 has to have a constant 12v+ as well as the fuel shutoff solenoid, labled as #3.

The constant power thing will do very little if anything to the performance. It is a minor advance solenoid that decreases fueling at low manifold pressure. I noticed nothing when I did this on my car.

so this step is not necessary to adjust the fuel? i could just skip it?

anyone?

Seemed to help my car, I'd do it. Takes about 10 minutes max.

I was just talking about providing constant power to the advance unit on the side of the IP. I don't know if the advancer is the same on a 1.6. As for fueling and turbo adjustment, they will definately change the performance of your engine.

so i guess i go back to my original posting, how do i connect these two?

anyone help with this simple task? i don't want to screw things up, just looking for advice from people that have done this before.

can i simply cut #4 and splice it to #3?

andy2 · « **Reply #14 on:** October 04, 2006, 07:57:50 pm »

Yes you can simply cut #4 and splice into #3,just insulate or cover up the remaining #4 wire so it does'nt short out on things.
