hey everyone, i just picked up a 2002 recon 250 es for free... the wires to the ecu 22 pin connector have all been pulled out from the previous owner. i havent been able to find a diagram for it but was hoping someone might have a picture of theirs so i can get these all plugged back in correctly. i hope i posted in the right section here. i have come to a brick wall as far as my search and would appreciate anyones help

That may not be the only thing wrong with the wiring harness, you'd be farther ahead to just replace it. You can buy a new (2002 - 2004 Recon 250TE) one:
32100-HM8-A50 WIRE HARNESS $144.91
Or a used one:

You can get a copy of the service manual HERE to guide you. Let us know how it goes if ya can.

Welcome to the forums!

thank you, i may go ahead and replace the harness, i put everything together and cleaned the carb, it now starts but wont shift the 2nd and 5th gear light stay on. cant get it to read trouble codes.

Thats why I didn't give you the pinout for the ECU connector. Hacked harnesses can/will let the smoke out of expensive electronic components (& wallet needlessly) in an instant. Wish you luck...

thank you everyone for the help so far, i have replaced the wire harness and am now getting three blinks on the first gear indicator, i have read on the forum about cleaning connections to the angle sensor and the computer, i did that along with electrical moisture barrier lubricant on the connections. i still had the same problem so i replaced the angle sensor and still no shift just the three flashes on number 1 light. after replacing the harness and the angle sensor im kind of short on ideas other then replacing the shift computer. any thoughts or should i go ahead and replace it, im guessing there isnt a way to test the computer short of just swapping it out?

What does the service manual say about those three blinks?

 

[geno13579]

it says issue in harness or angle sensor

Did you get new wiring harnesses for everything that is/was cobbled up, so everything now plugs in correctly as intended? Get the right part numbers to match the year and model of your bike? Finally, have you successfully cleared the previous stored code? Is there anything at all on the bike that does not function now, such as neutral light, shift switches, shift motor etc.?

Next up, check the gear position switch and the vehicle speed sensor. Then check the angle sensor (double check that it is installed right) again. Assuming the wiring is now corrected throughout AND everything else in the system works, the ECM may have become damaged.
