What exactly is PIN 7? It is the loop around the shielded wire. What connects to it? I am new to this obviously... could not find it in the search

Shielded grounding cable, goes to ground. It is used to reduce unwanted electronic (RF) interface/cross talk between components and noise.

thank you!!!

Your welcome Mike. So I see that you are converting your tii to EFI. What manifold are you using? 318i or tii/320s manifold?

Is this what I am looking for?

Yeah, the shield is the braided stuff off to the side. Where did you find the photo?

Hi Colin

Thanks again for your lengthy megasquirt post. We probably do need a megasquirt section and FAQ.

found the picture in yahoo searching shielded cable. Found that actual cable on eBay. They sell it in 10 foot sections.

Now I need the coil connector shown above. Cannot seem to locate that one in the states.

You just want to have the shield from the sensor wire spliced together with the shield from the cable going to your MS relay box. You should be using the shielded cable that MS sells for the EDIS crank sensor to avoid any electrical interference from alternator or other electronic "hash" producing devices. You have one piece going from sensor to plug on the EDIS controller and the piece going from the other terminals on the plug to the relay box. These two shields can be connected over to the other negative big black wire coming out of that same plug and run that to ground via the tapped hole with a ring connector on the rear part of the 318i manifold. That's where the factory grounded the stock FI system. Keep all the grounds for this system tied to one central point so you don't have any differences in potential to ground. This will cause problems with your FI.

Had the same problem finding the plu for the coil. Ended up buying a whole other system for $50 just to get the plug. Don't know why this is so hard to find. Thought that DIY auto tune would have it as they have pigtails for everything else
