Starting with the 86 EVTM it shows the PIP. SPOUT and Ignition ground wires with a grounded shield around them.
I suspect this runs the length of the cable harness and is to protect against Crosstalk.

what your saying i agree with and good info on the points posts.  the 22kR is spotted/ installed to protect the IDM pin 4 obviously.  I was about to discuss why the 22k is not spotted more upstream to protect all the DG/y wires which under my "misunderstanding" would protect the TFI as well as the IDM.

i guess whats confusing is the guy goes from no spark to having spark after the repair.  im going to check back in with him to see if this good spark is still the case.
