i posted this in the S chassis forum but someone told me i posted in the wrong section. So i am pasting my thread here i need some assistance. :wiggle:
Ok so i am in the process of doing a 5 speed swap as well as a new ka24de while we are doing the conversion.
I got curious and i looked up whether a 95 240 is a obd1 car or 2.
I came up with conflicting info.... Keep in mind i am unable to inspect my 240 because i am at work now. ( i spent saturday and sunday rebuilding my whole ka24de which is now done..but some things popped into my head.)
i notice that i got a whole 5 speed engine harness with the swap, well the plug that goes INTO the ecu is White (which seems like from my online reading is a obd2 harness...I also have a matching ecu.
SO, what problems am i going to face when i install this badboy into the 95 s14? being my car MAY or may not be a obd2.
here is my list of facts and unknowns as of right now
the engine swap i received has a ONE wire UPSTREAM o2
the engine harness has a big white connector that goes into the ecu
my 240sx may or may not be obd2 i havent checked yet.
the old engine thats still in the car has no exhaust manifold so IDK how many wire upstream o2 it had to begin with.
I will inspect my 240 after work but i am curious if anyone has some info regarding DEFINITE way to figure out what is obd1 and what stuff is obd2
Side note: i noticed that the harness has a huge grommet that appears to would pop into the firewall to seal the hole. I am thinking this harmess when it was removed went from the engine itself and down through the firewall and plugged into the ecu. if thats the case then i will install it that way... but will any obd1/2 issues occur??
