Map sensored ECU conversion problems

[parrot]

The detailed USDM electrical wiring diagram book is here http://www.aeu86.org/index/technical-ae8...topic=5158 and will show you what is required for the idle up circuit. I can only speak for the JDM loom which is quite different from USDM. The underdash loom contains the various diodes and the charge/headlight loom contains the VSV's. The engine loom has nothing of relevance.

Many people drive around with a non functioning idle up circuit but I found it to be a pain in the arse, and eventually sourced all the looms and VSV's. From memory the zenki looms used an external idle up computer whilst kouki were incorporated into the ECU.
