Initial set coupler?
Im trying to set my idle and adjust my mixture, and the FSM says to ground out the initial set coupler, and shows a drawing, but I cannot, for the life of me, find that friggin' thing. The drawing is for an N/A motor. Can someone please post a pic, or at least gimme a good idea where to look, and if possible, tell me what color the wires are to the connecter im lookin for? Its for an 88 Turbo II. Thanks! Brian

Look for a single green connector right next to the leading coil pack beside the battery in the very front of the engine compartment. There should also be a larger green connector right next to it.
|
It's a green plug, in the front right corner of the engine bay (right near the leading coil.) It has 2 wires going into it, orange and black.

Can someone explain what grounding it out actually does? I've never cared to do it when timing or setting the TPS/idle...

Jumper the single green connector to any ground with a piece of wire. You can use a plain piece of wire that has been stripped at both ends. Or, you can make up a simple jumper wire by putting a male blade connector on one end and a small alligator clip on the other. Stick the blade connector into the green connector and attach the alligator clip to any metal part that has a good connection to the chassis or engine.
I believe that grounding the connector takes the ECU out of the loop so that the BAC is disabled. |

I believe that grounding the connector takes the ECU out of the loop so that the BAC is disabled. FYI: Series four have a two socket, green connector that you jumper the two sockets to *set* the initial set coupler. All that does is FIX the BAC's duty cycle and nothing else. If the rpms are under 1200rpm you don't need to do this imho. |
Oops! I didn't know that the S4 was different. Sorry for the misinformation.:(

Yep. I actually got fancy with it and crimped a spade connector on each end of a short wire so I can plug it into the connector, I got tired of twisting the ends of the wire to fit in there.

Way to go resurrecting a 14 year old thread. Back probing a connector would seldom need done unless it is plugged into a mate. For instance. the leads of the meter won't say on/in the front without holding them there and you don't have a helper while needing to turn the key on the ignition or similar.
