i bought a obd2-obd1 conversion harness, and it was a little screwed up. i need to put in a new ecu pin so i can connect a wire to it on the other side. anybody know where to get one? i can't find one locally.

 

Try the dealer, an electronics parts store (not BestBuy) or send me the old one in Japan.

Or just bypass the entire adaptor (this one pin) from inside the ECM to your adaptor harness. Requires a hole and some soldering technique.

Can you remove the pin from the connector???

 

or hit the junkyard homie...tons there for relatively nothing

 

this is the connector that would normally be on an ecu, i can't just find pin this at a junkyard. i tried a couple different radioshacks and they didn't have it. i guess i'll try the dealer, though i don't know if they'd sell something like this seperately. i was hoping someone had a web site with stuff like this.

umm i definately pulled ecu pins from the junkyard...but its your time and money ...you find a connector...remove the wire with the pin..snip it so you have enough wire on the end of the pin..and use that for whatever youre trying to connect..its kinda simple

you're not understanding this. this isn't the connector that stays on the car. this plug would normally be found attached to the ecu, as a non-removable part of the ecu. you can't just 'snip a pin off.' its really not that simple. i actually had a abs computer with the same type of pins in it. i took it apart and tried to get one out, but they're all held in place by a big chunk of plastic that makes it impossible to get one out. i need find a place to just buy the pins separately.

 

if they are so hard to get them out...how in the world are you going to get one in??

You said you needed a pin for the obd1 harness you have...

if youre putting the ecu pin in the harness you can find these at the junk yard...

Now youre talking about the pins on the ecu itself...Youre not making it clear which one youre trying to find...because now youre clearly talking about something other than what you first posted

are you even reading my posts? if not, then get outta the thread. you're not helping me by posting crap without reading my replys.

do you know what an obd2-obd1 conversion harness is? do you know what it looks like? if so, you'd know the end of the conversion harness that the original ecu plugs go into is the same as the end of a obd2 ecu. you can't just go to a junkyard, rip apart an ecu, pull a pin out, and walk out. these pins aren't connected to any wiring on the car; they're inside the ecu, and other electronics such as the abs computer.

i'm talking about the one and the same thing the whole time. this is a obd2-obd1 conversion harness i'm asking about here, it'd be pretty hard to find one at a junkyard. not a lot of people convert their cars from obd2 to obd1.

 

dont insult me...cause youre pretty ******* dense...Im trying to help you but youre acting as if you already have the answer..

Read carefully..

A: my car has the same harness (98 ls with an obd1 b18c)
B: GO TO A JUNK YARD..THESE PINS CAN BE PULLED FROM ALMOST ANY CONNECTOR ON THE CAR (THERE ARE CONNECTORS WITH MALE AND FEMALE ENDS..DOESNT TAKE A GENIUS TO GUESS WHICH ONE YOU SHOULD EXTRACT A PIN FROM)
C: Ive done what im telling you to do...

 

any computer parts store should have them in stock (a computer building parts place not like compusa). I have some OBD0 ones if you need them but I'm not sure they are the right size

 

also do you need the large or small pin? there should be two different sizes

so are you saying that the same size/type pins can be found on other plugs in the car? if so, then you should've cleared that up. it sounded like you kept saying to pull the pin out of an ecu plug, which wouldn't work because the pin i need is on the ecu itself.

hmm, i had no idea a computer parts store would have it. i'll have to find one tomorrow. you're right, there are 2 different sizes of pins. i need the smaller one.

I tried to explain things to you but all you kept doing was telling me Im not reading your posts...

you say that i'm talking about 2 different things. people that know what a conversion harness looks like know that one side of the harness has an ecu-type plug. either way, i appreciate the help.

 

i BUILT MY OWN BREAK OUT BOX (B.O.B.) CAPS sorry, I pulled ECMs and some length of engine side harness from junk cars (free), desoldered the plastic connectors from the ECMs and made my own harnesses for use to diagnose with my portable oscilloscope and laptop.

If you cannot find a like pin from another control unit then you will have to buy a cheap ECM.

Or you can do what I said the last time. Drill a hole in the plastic where the broken pin is, insert a wire and solder it to a piece of that pin that is still on the circuit board inside the ECM or completely remove that pin (desolder it) and solder the wire directly to the circuit board (I vote against direct connection, mother board doesnt like too much heat), splice your new bypass wire to its partner on your adaptor (crossover) harness.

I use a handheld propane torch to desolder the entire plastic connector and all of its pins from the ECM mother board and toss the ECM. I learned that I need to attach the other half of the harness that I also cut from the car (now I have the male and female halves) to act as a heat sink. In the beginning I was overheating the ECM connector and melting the pin plastic holes and the pins were no longer straight in the plastic connector and would not align up with its mate (engine harness).

The pin that you need is shaped like an L on the back side of the ECM plastic connector on the inside of the ECM, I use a wire twist tool to put wire on the L pin and solder and shrink wrap to build my extension harness for my B.O.B., you can just twist the wire on by hand and solder and heat shrink wrap if you like, right near the mother board, feed the wire through the plastic connector, drill another hole in the top (or bottom) of the plastic connector to feed your bypass wire to your adaptor harness, spice in, solder, FIXED. Chalk it up to experience.

 

that sounds really fucken complicated, i'll just try a computer parts store first, and a junkyard after that.

 

i think this guy has few of them..is that what u looking for?

 

who exactly is 'this guy'?

 

i have no idea..i was looking for a side molding n saw him selling ecu pins so i remembered about someone posting bout ecu pins n i threw a link for u to check if thats what u looking for

you haven't provided a name or link or anything. who are you talking about?

 

oh yea..i just noticed lol i have to look for it now

 

ok, i still can't find this dam pin. the dealer doesn't sell them seperately. computer stores don't have them, i tried 2. i tried radio shack, nothing there. i looked at a junkyard for these and i can't find the correct size. in the middle of the pin its very narrow, and the pins off of regular plugs are way too big. this is the 1 dam thing i need to find before i can get my car tuned.

anybody have any other ideas on where to look for this?
