Been cleaning up the engine bay of this 1978 Royal with a 403 engine I recently aqquired last week from rat crap and chew... which has damaged hoses and wires
I marked the spots on the picture with letters to help me identify where some hoses/wires need to go

A - I believe this is the connection for the temperature reading ? which would go to wire E or F
B - Hose Connection to i believe a check valve? and then to hose connection G
C - Hose Connection to some unknown device which would then connect to D
D - (see above note C)
E - Broken Wire connection
F - Broken Wire connection
G - (see above note B)
H - Unknown hose connection
I - Unknown Connection
J - Hose hanging on passenger side of engine, unknown where to connect


I know the hose from the middle connection of the tvs to the distributor is missing and will be replaced as well
Any thoughts at what is shown, and i have closer up pictures as well from different angles (links only)

Oversteer is when you hit the wall with the rear of the car, understeer is when you hit the wall with the front of the car. Hp is how fast you hit the wall, and torque is how far you take the wall with you when you hit it.
