Iginition module location 87 dodge ram pickup

trying to locate ignition module on 1987 dodge ram 50 every one says it is on the fire wall but cant locate it there ... found voltage regulator but no ignition mod ..if anyone has a clue .. please respond .. thanks

On my Dad's '86 it was under the driver's side of the dash.

'87 was the first year for fuel injection so it could be somewhere else? I dunno.

I am having same problem.. Did you ever find it? someone even said to me something about the battery but still no dice..
