Folks, I have two problems stalling my swap (LS/Vtec into 89 CRX). (had ZC motor in it). I've done the physical engine swap, coolant, vacuum, and gas line junk. I removed the engine harness from the old ZC and grafted it onto the LS/Vtec (that I'm going to run an OBDI ECU). The TPS, TW, TA, EACV, all hooked up fine. I couldn't find a map sensor nor MAP connector on the ZC motor. There was a white connector that was tied off at the back of the motor to the rear block/manifold brace. I tried to hook this up to the GSR throttle body MAP sensor, but it doesn't fit, so I don't really think its a MAP sensor connection.

I know this sounds stupid but did the ZC come with a MAP sensor? I sure as heck can't find it. The throttle body only has a TPS sensor.

Also, please confirm the following bad news. My GSR head is 1996 so it's OBDII. Therefore the injectors not only will NOT physically fit my engine harness (I've already tried 'em), they are the wrong type being high resistance, low current, saturated injectors. So I got to find OBDI injectors, right???

Thanks, Dave K.

 

the MAP sensor for the ZC is not on the motor - it is on the firewall, near the center at the top - yes, you will need different injectors for OBD1
