Can someone help design a 5 volt circuit
Yes I realize this is an RV forum but the post is related to wiring on my tow vehicle. I have a diagram below of what I am trying to do. But I will spell it out as best as I can first. My hope is that...

Yes you're pretty much on the money. I initially didn't want to get to far into the computer details because I didn't want to cloud the waters or dissuade suggestions because it sounded too technical. So I left it as I have a 5v out and 5v return that I need to make work with my one old school NSS.
Donor was a 93 Mustang GT AOD automatic with a C3W computer. It was a complete swap, motor and harnesses but no transmission. It is smog legal in California with a BAR label on the door. I do have the extra wire available but unfortunately I did this swap 20 years ago and don't remember the actual pin numbers. I just have the two bare wires free under the hood next to the self test connector.
To pull codes I twist the wires together. Then I jump the STI connector to the diagnostic connector and read the codes from the blinking check engine light.
I'm assuming when you are talking about tricking the EEC into thinking I in park (that the NSS is controlling pin 30) that you're referring to me twisting the two wires together.
I've run like this for 20+ years with no issues. My hope is to design a system that when it's in park the EEC knows it's in park, and when it's not in park the EEC knows it's not in park. PLUS I need the NSS to safely control the starter solenoid.
I've received a lot of good ideas off this post and I'm going to try a few of them out on the bench and see what I can come up with.
Thanks for the ideas on the double relay by the way I really like that.
Thanks
