I wished I would’ve seen this video 15 years ago. I didn’t know how to shield the wire, so I just made tape out of regular aluminum, tinfoil. Shielded everything with the aluminum tape and then covered it with electrical tape all the way over the connectors, never had another backfire. We made numerous calls to Holly in order to get the same information you have provided, but we’re never able to get any information from them. Thanks great video.
Great video. I was looking for shielded cable wire videos a few months ago when I had to make one for cam crank signals I'm not a wireing guy this is the best video to break it down
Glad to see this attention brought to just a sensor and harness. In this world where techs still learn how OBD-2 works after 30+ years, shielding becomes more important than ever! Holding 28+ seminars including serial data, I bring up star-washers for good grounds. Dielectric grease in connectors, in terminals, bulbs, the flashlights in their tool boxes. As you twist shielding together, I often cut it long only to fold over to fit tighter in the connector. I like shrink tubing and have spools of 3M of two popular sizes. Even the LS swap and Fords, but this is new technology and must learn new ways. 90% of techs never check alternators for A/C voltage on a DC circuit that results from bad diodes as power demands increase. This is internal noise from 0.010Vac to 0.060 Vac at 2k RPM with a load or not, at the alternator. 1/3rd at the battery as it acts as a capacitor / calming the ac voltage.

Great tip. Had a 91 Honda accord and under passenger carpet foot area I found a large shielded cable that went to ground it was interesting. They been doing this for years and it’s good that people should know about this.
Great job on explaining the electrical background and the ways to do this! It feels odd coming from an industrial electrician background to hear the automotive aftermarket more or less just starting to talk about this. It is standard for decades in the industrial environment to run all analog signals and high speed signals in shielded wiring to any kind of PLC.
This is amazing information. I did not know. I was literally just trying to get my speedometer to work the other day on my 700R 4 and it’s going to a digital dash the wire I was messing with had this measure around it and there was only one wire will look to be one wire coming out of it now I understand why it doesn’t work and what I did wrong. Thanks for the tip.
Fun coincidence, I just watched this video on my midnight dinner break last night, after hand fab-ing a bracket for the *RIFE's Speed Sensor I'm installing on a friend's ZX14R Drag Bike* (it has your 2 1/2" reluctor wheel on his offset front sprocket as well). That and, it will have *Rife* IAT (two, with one being in the Dry Block), along with your Oil Temp., Fuel and Oil Pressure as well = I ❤Rife Sensors 😎
Belden style shielded twisted pair wire? 18awg conductors with the foil and the ground? Absolutely correct on grounding only one end. It's done the same way in control wiring for residential/commercial/industrial low voltage and canbus control wiring.
One thing that I do for all of my shielded wires is pull the braid back over the sheathing before recovering down the solder sleeve. Helps prevent any potential shorts from the shielding to the conductors, the only downside is having to size up the raychem solder sleeves when dealing with larger bundles.
When passing the shielded wires through a bulkhead connector, can the shielded wires share the same pin? Let’s say I have crank cam and wheel speed. Do they each need their own shielded wire pass-through (3 dedicated pins) or can they all be combined on the same single pin?
I got a 2000 gmc 3500 bucket truck cab & chassis w/ dura lift man boom lift , the vss wire is shielded , the abs ground runs down to the vss sensor at the transmision , the computer is right next to the ans module driverside inner fender , the vss wires run to that computer nothing is hooked to the braides ground by the computer ..they ran that abs ground all the way to the transmision and hooked into the other end of the shielding wire , its gotta be in the wrong spot , where does my abs ground go ? My wire diagram is out of haynes it dont show a abs module , it shows 8 coils and 8 injectors , i got one coil and tbi ..
I have watched a lot of guys hunting down problems that had to do with shielded wire... We also do twisted pair inside shield as well.. Not even worth telling most guys, they won't listen...
There is much better wire then this. You want a good Dual Shielded cable that has a drain wire running through it which you then ground rather then just soldering to the shield itself. All drain wires should go directly to the battery ground not a chassis point. Look into high quality CNC cable MFG to understand proper cable assemblies.

Great video......I needed this

Good Stuff Guys!
Awesome video great content👍
Cool deal!!!!!!

The shielding ground could be combined to a single pin to pass through.
I think a cleaner method is pull the wire through the braid at the bottom of the sheath

Be careful with the wire using the heat shrink/solder butt connectors, some pvc wires/cables won't take the extra heat. Might melt the jacketing.

Thats confusing as for example Haltech says to only earth the shield at the ecu end.
@@najstephy5565 that’s what the video is saying. Dont do anything with the sensor end, ground the shield at the ecu termination end
@@MotionRaceworksOfficial yeah I get that part but I was pretty sure it goes to the ecu ground and you were mentioning the chassis ground?
@@najstephy5565definitely don’t feed signal shields into the signal -ve
seems like the bots liked the show as well. lol
