Lockup 904 transmission

I have no idea, but the A998 from my ยด88 Dakota has got the connector in that same location.
i've got one out of an 85 5th ave. in my dart that has hydraulic lock up. was told around 87 they went to electric lock up, which is what that plug is for. i know i looked at an 87 5th, and it had the elec. lock up. dave.
