    All dash lights lit up with no key

    I finally got this m50 e30 swap ready to try and crank. Have a few issues because it wont start but does crank

    1st one I need to solve is that all dash warning lights are lit up even with no key. Is there a relay that might be stuck open for this? I fully expect warning lights but they shouldnt be on with no key. Something is giving it power.

    Which warning lights are you referring to?

      All of them.. every single one on the dash even with no key. I traced that my dme and fuel pump grounds are seeing power.

      Something is shorting grounds out so I have constant power. Have to find where the common ground for thkse are

        Started tracing wires and found this.. doesnt seem very factory to me.... and they all have 12v with no key
        the patch piece goes to one of the green ignition wires

          oh wow, you have some troubleshooting to do. Find out why this was done in the first place. Were they trying to hook up an accessory to constant power? A wideband controller perhaps? Alarm? it's usually something aftermarket.

            It had a viper alarm in it... Im guessing the alarm spliced here.

            2 of the green wires go down to blue cluster plug and warning light. 1 goes to ignition switch(the one with heat shrink).

            Should these cluster wires li out at the big C connector that runs into bay?
