Dan Wheeler's Remote TFI ("Closed Bowl") Conversion Thread

[DPDISXR4Ti]

I don't see disconnecting any ground as an advantage, unless it's proven to be causing a problem.

That's typically been my position as well. If you take a look at this thread there may be reason to think otherwise....

Something is contracting the full URL of that thread and the link doesn't work for me.

Per that link, the mentioned "Golden Rule" bears thought & consideration. Very definitely do not do something like ground both ends of the shielding of a shielded cable.

I would also eliminate that blue connector thingy. Those are an electrical fault looking for a place to happen.
Not implying anything, just some light reading on wire terminations that I've recently learned of and seems appropriate to mention:

Thanks for the input. So I'm guessing that grounding both ends of a cable shielding is a textbook case of a grounding loop?

Great article on the "marine grade" wire termination. I'm saving it to read again. I didn't even get to the second link yet.

I knew someone would poke fun at my blue "high-tech wire nut". I take no offense. It's a Swenco Posi-Twist. I've used their products in the past (https://www.posi-products.com), often on a "temporary basis", only to find them working perfectly fine 10 years later.

I don't know about it being a textbook case because I haven't read any books on the topic. I do know that when we were having trouble with the data acquisition system on the dyno getting poor data due to electronic noise that such a thing was pointed out as a very definite "DO NOT DO THIS" by the consultant that was hired to sort out the problem when our MS-EE and various Phd's couldn't.

Not so much poking fun at, just concern. I know all too well how something temporary is still there a decade later. Usually causing problems, but not always. I try hard not to give Mr. Murphy a reason to visit.

yeah, the smugmug site hosting all my pics was $45/year and I wasn't doing much else with it so I let it expire I need to sit down and re-do those threads with a more reliable image source.

hmm, yeah - you're right the dist connector is the same, just the TFI has one small difference which is that the 3rd pin from the top in the diagram goes to +12v on start only for the gray but goes to EEC pin 4 for the black. That's the only thing I see different. I'm not sure if my current "grey" harness has the 22K ohm resistor already in place. RJM's website seems to have disappeared so I don't have the wiring diagram to check.

so I should just get a grey remote TFI then without the 3 spade connectors?

X2 I was looking at your threads and was like he is referencing a pic but there is nothing there...
