this is the plug and wires from the distributor on my b16, can someone plz explain this shielded crap to me i just dont get it, the open wire wrapped around three color coated wires that goes from nothing and hooks to a ground?

 

im trying to redo my harness and ive seen this in my diagrams but i didnt really know what to expect until i took it apart and i just dont get it....do i need to wrap wire around these three wires if i make a new one?

 

the idea of a sheilded wire is to "block" ign/ electronic noise from getting into the signal wires. if you get noise, you get erratic signal, then you get problems, misfire, erratic timing, ETC.

do no connect both ends of the sheild to a ground, only one end gets the ground.

 

thanks this helps, does it need to be there though, has anyone ever redone it without the shield and had problems, when i redo it ill wrap it for security just wondering though

 

its like insurance having that sheild on there.

i highly recomend keeping it.

 

also, there are a few shielded wires that just connect from one wire to another, it doesnt wrap around the outside of the wire....like my ground H that goes to the ecu, has an open silver wire that connects to the the black/red to the white wire on my o2 sensor, it shows shielded on my diagram, but it doesnt shield it, it connects to it, there are a few that way....if you look at the diagram, it shows 3 different wires shielding the wires on the dizzy, but actually only one does, and it only shields the 3 in the pic, not all six..........sorry if im confusing, i can take pics of other wires if you'd like

 

you o2 signal wire should be sheilded, are you sure the wire you are looking at isnt just a "jumper" to ground the shield on one end ?

i know what you are saying about the dist, it might only be shielding the high side or the low side wires.

for what its worth you can get new 6 wire w/sheild (single run, with 6 individual wires and sheild) this might be a better option for you, rather than splicing all kinds of stuff together.

contact Tony @ www.T1raceparts.com he should have everything you need (including new pins for the plugs)

 

awesome, youve been a bighelp i have been looking for pins for about 8 months now
