Ever thought that you would take the easy way but it ended up the hard way?

Ever thought that you could do something easily but the more you did the more things that had to be done? (knock-on effect)

let me say at the outset that I am gonna finish this as an auto CA18 conversion

BUT..... I have been studying the S13 workshop manual for the electrical hookup of the auto box and it is leading me down a path that may not be well trodden.

1. Has Anyone done this before - CA18 + Auto from Silvia into 1200 Ute?
2. Do I need to use the Silvia ELECTRIC speedo and tacho and warning lights?
3. All these sensors! - fluid temp sensor, revolution sensor, speed sensor, kickdown switch, Soliniods for the shifter selector

Ok I need some plugs that fit the plugs on the auto and shifter, maybe a speedo, (how far do i go?) if no-one has them i will go try the wreckers.

Any experience on this would be appreciated. if not i will document my journey in my build thread
