that swap was from a 95 motor to a s13 car. Mine is a 91 motor to a s13 car so its less complicating can i use my single cam harness for the twin cam motor or do i need a twin cam harness?

Hey bro, My 89 240 just thru a rod thru my oil pan and I'm in the same mess, I've tried to find a KA24e, no luck. SO instead I've Opt for the SR20det Black top, you can get this set up with harnesses and 5-speed transmission and all the goodies you'll need for the swap even 100% start up.. Best bet is to sell the KA motor and invest in the SR motors, more aftermarket parts available.. Sorry if it's not what you wanna hear, but I've searched everywhere for a harness in good condition, if you find one it won't be intact or brittle and falls apart.. I'm having the issues like you and I work for Infiniti/ Nissan.. Go figure.. .. Look at Jazzproparts.com.. great prices..I'm not affiliated, just sending you an Idea as a 240 appreciator..
