The 8th generation Legnum/Galant uses a really simple method to put the car into a diagnostic mode to flash out the error codes on the dash. You just put a jumper wire between pin 1 and 4 on the ODB2 port and turn the ignition on. However, I’m lazy and I’m over looking for the bit of wire I’ve left in the car and then having to awkwardly bend under the dash to insert it. So I came up with this solution.
Core Electronics sell the ODB2 connectors for $2.65.
The pins are neatly labels as well, I grabbed a pair of pliers and bent pins 1 and 4 inwards 90 degrees.
Then soldered an offcut of wire across them.
I will eventually fill the plug end in with epoxy, a small loop of string will be embedded to help remove the plug from the socket, it will also protect the pins from shorting.
