Ok so the harness im dealing with is a MESS. id love to buy 1 for my 88 crx si but tough times calls for shitty decisions lol so heres my problem

Im running a b18 from a DA integra the fan switch is located on the back of the motor and the harness is different to me cuz im used to dealing with 92-00 harness's. question is how can i get this fan either to stay on or come on by command.. which color wires do i need to look for to tie together because most of the clips are broken/ cut off.

2nd what color is the single wire for the temp gauge and if i dont have it cuz its been cut how can i run it straight to the ecu and what not. thanks!
