97 f150 Wiring Harness and Speedo Qestions
I just replaced the engine in my 97 f150 4x4 4.6 romeo with another 4.6 romeo from a 97 crown vic with less miles. now im working the bugs out i have a extra plug on the drivers side of the engine harness i have no idea were it goes its just after the oil sensor on the buttom at the very end of the harness. also now my speedo dont work but my trip still counts miles i wouldnt think thos two are related but they could be. iv looked high and low in my hayness manual too no avail. I havent checked the plug on my transfercase yet its barly 40 degrees and the wind is blown 90 too nothin out there ill probly finsh up tommro. so if u have any idea whats up with my speedo or where that extra plug goes let me know.
and all google seems too know bout the wiring harness is were i can buy one for every model of vehilce except mine LOL
oo ya every thing else seems too work.

make sure the VSS on the extension housing aka the back of the t case is hooked up. also there is a bunch of wires that go into like a box looking thing under the dash on the left side... anyway it has a bolt that goes thru it and tightens it down. make sure that bolt is tight because when i loosened mine once my speedo quit working and so i tightened it back up and it started working again... coincidence? i have no idea but might wanna try that.

ok ya i may not have goten the bolt tight. I just checked all the fuses and the plug on the transfer case and that all is good. ill check my plug and see.
Update: checked the connection tightend and cleaned still doesnt work but my cruise works just fine
so iv been doin some searching and found one other simalare problem with the speedo every works but it and the last post suggested that the speedo it self had gone bad. so i think i will replace all fuses with anything too do with it just for good measure and if that dont fix it ill replace the cluster.
still need some input one what the plug just after the oil sending unit is i cant find anything online bout it.

LOL if u google long enough u will find what ur lookin for. i finaly found that plug and its just a extra for "That's an extra connector used for the "WABS" - 4 wheel brake steering which you don't have. I think that was on the Navigators or Expy's only." found the answer on another forum (http://www.f150online.com/forums/v8-...307-308-a.html) but i was worryd this might be causing my missin out problem that im still tracing out. i swear every time i do somthin major too this truck i end up speding a day traceing down a miss fire awell just a quark i guess.
so now im down too just tryn too figure out whats up with my speedo like i said every thing works including cruise and trip so my only guess is that its in the cluster itself maybe from sittin in the cold for almost 2 wks without bein ran every day. tommro it will be warmer so i will get the miss worked out i just replaced a coil pack for the 2nd time
just out of autozone warrenty too
Update 12/10/10:problems solved STUPID AUTO ZONE CRAP lol bad plug wires was the cause of the miss these were the boch 70 dollar wires for my truck so life time warrenty but i had just bought them back in aug aw well now i have new coil packs wires and plugs so im set for a while. my speed started working again i hit 65 and taped on the cluster and it started working again so i asume its a lose connection not worryd bout it as it will be a spring project lol TY lifted for the advice

also dont buy that autozone crap. become friends with someone at a ford dealership and get motorcraft parts. i know this is a suprise because it was to me but i get my motorcraft oil filters from walmart for like 3 bucks. ha

you know what is a weird deal is that i had a charging issue with my 98 and i got frustrated because i literally replaced everything in the charging system and eventually ended up hitting the dash right above the cluster and my truck started charging again... havent had the problem since. weird. i know.
