    Did you check for blown fuses? The radio has two fuses, Radio No. 1 (15A) and Radio No. 2 (7.5A). The cig lighter has its own fuse CIG 15A. The oil pressure gauge not reading is probably due to a wire fault if the other gauges are working.

The guages from the japense car the engine was in are in metric units, so they measure differntly. The sensors should be physically identical, every engine is made in japan.

No electrical power at all checked grounds,fuses,relay,etc 1989 none turbo supra with sport package

Check for a grounded positive wire from the battery or alternator. This could be in a wiring harness or actually in the Alternator or Starter. First disconnect the Alternator and see if you get power from the battery, if no reconnect the alternator and disconnect the starter and see if that allows you to get power from the battery, if no you have a grounded positive wire that is causing a short.

You are going to need a repair manual for your Supra before you start. I have one in my shop right now for another problem and I took a look under the hood. I wouldn't try it without one. The manual will give you the step by step with pictures.
