Hey all. So our 1994 e320 wagon isn't starting. I've read it can be the fuse , neutral safety switch, and the security system.
I cut the NSS wires and tied the purple ones together. Same thing.
I read hear about a "14 pin connector at the ATA"
How-to: Disable alarm on a 1993+ W124 post number 23.
What and where is the ATA ? I haven't found anything in my searching.
To just jump the starter and make sure it works , I am trying to use the 3 wire block that is by the battery. How do i do it again ?

I can't remember. I read Connect a wire from the battery to middle . But that did not do anything. And the middle wire is hot anyway.
Thanks !
