MAF Wiring

[Blacksheep Josh]

I've been thinking about extending the wires connecting to the MAF electronics, so that I can orient my filter behind the driver side headlight. It would give me more room, and be less travel between the filter/maf to the intake.

I also kind of think it'd be cooler because it wouldn't be next to the engine when idling, and there's enough room to build a heatshield, and be able to do a good job of it.

So I have 2 questions:
1. Would extending the wires that connect to the MAF matter as long as I match everything up? I'd also try to keep the wire length's the same as well.

2. Does there need to be a minimum distance between the MAF and Throttlebody? Or does this matter just as long as the MAF is there.?

Thanks for your input.

make sure you use the same guage wire at least so that any inpendance cause by the add'ed wire does not mess up the maf electrical supply...like if you went down in size ...may cause interference ohm or amp wise to the sensor. for the length.... if you think about it the factory wireing could be moved back towards the cab so i'm thinking that adding a little more should not be such big deal ....if you REALLY make the wires longer then i forsee the same issue i described above .....causeing more of a load current wise to the sensor and throwing the calibration of the maf off or the cel light goes off.

I didn't even think about that. I won't be doing this for awhile, so I wonder if possibly how much MAF wire is there under everything.

I'm also wondering if perhaps to beat the impedance problem with more wire, if going up maybe one size would help. Let everything flow better.

thoughts?

well if you deal in the ac world ....the further the distance the bigger guage wire(numerically lower number) you need to handle the increase demand in amps( like if your tapping off a 120v line that is feed with 14/2 romex to extend that more lets say 50ft more distance then useing 12/2 or 10/2 with meet the demand for the new outlet) ...for dc ,hmmm... i know that stereo amps run better if they have a lower guage wire feeding them so to go one size bigger may not hurt it but going smaller i bet would cause some issues....like if the maf requires for example 1 amp to properlly run and function normally then going lower in guage wire may starve the electronics because now it is now haveing to pull that 1 amp through a smaller wire and may now only be powered at the maf @ 3/4 of a amp .

phewww....:scratch: i have not had to do that much explaining in a while about wires like that lol .

i don't know ... just see if you can undo some of the harness's loom and see if you can't get more lenght out of it before you start to cut anything .

Yeah, I definitely plan to do that first. I'm thinking there may be some hidden length in there somewhere.
