i have had my wideband for a while now and since i did the engine swap i must have overlooked its wiring harness placement becasue it is melted all over the header, and of course, doesn't work. so i took it out, cut it all up and spliced everything open and at this point it is cleaned up[ nicely and i could solder it all back together with no problems, when i cut the melted section out it all cleaned up very nicely. but my question is this, from the wires making contact with each other, could it have shorted out the module or could it really just be as easy as soldering it back together and re insulating everything properly and what not?

thanks in advance.

with electrical problems i always check things 4 or 5 times.
yes you could have burned other things out but you will never know for sure if you put it all back together and then test it.
before you do any soldering test it out and see if it works. if necessary use alegator clips to connect the wires and give yoursefl more room.
only then solder things together - ONE AT A TIME! then start it - and only if it works do it to the next wire. that way you will know if your soldering is working and what wire is screwed up.
you can also check the wire at both ends - plugs - but that is easire to do when the entire harness is out.
if you put them all thoether before soldering then you can bet its module. or if you want you can go with your chip, it does not weigh much, and see if it runs on another car, or if your speed shop can check it out.
but no i would not solder eveything together, heatshrink everything, then find out it will not run and have to take it all apart to see if its your soldering.
dont forget a fuseable links.

thanks for the reply, i had it out of the truck and sitting on the work bench, i had a nice clean work environment which made it easy to just solder it all up and shrink wrap it all and wrap it with 100 pounds of electrical tape and split loom and everything, if it works it works, if not, ill need to save my pennies for another one, my solders will not be a reason why it doest work. iv got high hopes for it, but with my luck, it probably wont work.

your idea of testing it is good, but iv got no means of doing so, it needs a power and a ground and then id have to remove the gage from my truck and the sensor from my exhaust to get a reading from it. i just look at it like this, my solders are 100% good, if it doesn't work, it becasue the unit is fried and then i waisted an hour of my time for nothing, not a whole lot to loose in this situation, just time, which im willing to put every spare minute i have after school and work into this damn truck so it really doest matter, if i had free time not working on something for the truck, i wouldn't know what to do with myself im so used to it at this point lol.

Now make sure you didn't blow a fuse from the power source since the wires shorted out.
