if I can find one I would prefer not to disconnect and do the K relay jump if I can find one easy and cheap enough.

TIA

Do you mean the convenience relay under the drivers rear seat?

No... the black box under the passengers footwell. The one with two plugs but the later one that also does ignition interlock that prevents the starting when the alarm system is engaged

I think this is the part number?

124 820 56 26 [09]

But it is the same in 93 as in 89 I am told. And the black one of the two under there... the other being a Sliver box but that one is Cruise control.

Not sure I understand. You said same in '83 as '84? You mean '93 & '94?

I have one from a '94 its a 1268202426, but I thought that is the radio code relay, and that the alarm was handled by the relay under the rear seat. But hey, what do I know.

Dag nabbit... yea ... I mean 93 or 94... sorry about that.

Will edit to correct. I need a 94 is what I need.

Far as I know, and from my Indys directions it was under the foot well where the earlier ones were.

But it is also involved with the Radio as well as that displays the alarm and non alarm light within the radio.

Not sure he is right or wrong in the 94's or not. It is about the same sort of box and location as a 90 that I looked at though. Now you have me just as confused. Let me post a related question thread in the main tech and see if anyone else can weigh in a clarify it for us.
