Ignition system, battery to starter/solenoid

Hi everyone

1969 Dart, 225 /6, 904 trans, no starter relay or battery +ve cable.

So, I'm getting close (or thought I was) to lighting up my /6 and realised that I actually do need the starter relay to tie the driver side system parts as I reference them (battery, starter relay, starter/solenoid) with the passenger side system parts (ballast resistor, coil, dizzy, plugs) or do I ? From the FSM it looks like the 'I' terminal on the relay is the link between the two sides of the ignition system. Given I don't have the relay yet (will order it of course) can I simply run a jumper from battery +ve to the terminal on the ballast resistor receiving the 'ignition 2' feed and running the 14DBL wire to the coil and put a switch somewhere along this jumper to act as an pseudo ignition switch in the meantime ? Apologies if this sounds like a baffoonish idea.

Second issue is my 904 is stuck in 2 gears and I'm not sure which 2. The control lever is bent like a 9" nail (I don't know how this is possible or why it happened) and gets stuck on a tranny boss so I cannot move it and I'm not sure which gear it's in but think it's a drive gear given the angle it's sitting at. This leads me to think I must isolate the rear wheels (prop shaft remove or jack stands under rear axle housings) as with no starter relay and therefore no NSS I might just propel the car out the garage like a rocket if the engine fires. Very difficult to get to the control lever and kickdown lever with the tranny and exhaust pipe in the way so will either remove prop shaft or lift rear end (likely the latter).

Cables, can someone please take a pic of their 225 /6 +ve cable set up as I'm flying blind here. I've got the -ve cable running from a driver side engine mount bolt to battery and the ground strap from the head to the firewall. I'm good there but they will both need replacing as they're both ratty. The +ve cables online seem to have an extra cable (black - ground ?) running the length of the thick red +ve one going to the starter. Maybe this is for a 1970 and later year and will look at that FSM to try and figure that one out. This is certainly not a 1969 setup as I can see from the FSM. Seem to be few examples of the +ve battery cable set up for the 1969 225 /6 so any pics from your cars or online resources where I could buy these would be great. Maybe I can just drop this black cable or use it to replace my ground strap cable. You guys know and as my wife tells me, I know nothing.

Edit: Here's a reference to that black wire following the hot starter cable.
