Hello i have a 1995 honda Civic and i cannot get my a/c compressor to kick on , only by jumping it

JDM k24a with NO vtec pressure switch/ so its blocked off and my connector is hanging.

Everytime i turn the a/c button on the fans come on, but the compressor does not kick on
it is wired just like hybrid racing's guide, BUT it ONly kicks on when i add power to the compressor.

ive disabled multiplexer, vtec pressure switch, and checked USE VTP AS AC SWITCH.

Ive connected A15 BLK/RED on the (STOCK ECU CONN) to E18 (MINES IS EMPTY SLOT)on the (RSX ECU CONNECTOR) using the supplied yellow wire.

recharged the system with 19 ounces of Freon , brand new compressor came preloaded with 3 ounces of pag

Ive Connected B5 BLU/RED wire on the (STOCK ECU CONN) to B9 a BLU/BLK (VTPSW) wire on the (RSX ECU CONNECTOR).

Edit:

A/C compressor still not kicking on, only when i manully apply power to the compressor.

thanks any help is appreciated !!

you would have to follow the path of the AC signal in the car’s and conversion loom schematics. it is a simple serial connection of all the devices that can disconnect the compressor.
