electrical help

so im swaping in a 2001 2.5l ranger motor into my 1996 ranger do i swap the computer and the wiring harness or can i us my old wiring harness and just swap computer because i dont have the wiring harness from the new motor

 

[Ranger Sport Honduras]

never had done anything like this, but u should swap the harness too, maybe they are different

 

[remington115]

does any one know?

harness is diffrent, i learned that the hard way form a 94 to a 92. i tried to swap the motor in my 94 to the same size in a 92 and the harness didnt work. everything was on the opposite side, seemd every couple years they change it. an 01 would have all kinds of extra stuff your 96 has.

 

[remington115]

well it's a little different because its from old to new not new to old and im also using a bunch of stuff from the 96 motor and some of the stuff from the newer motor is on my old motor so i think it will work

 

[remington115]

any other opinons

 

[scotts90ranger]

they should be similar enough to use the stock wiring harness, could even use the stock computer, but I don't know how much extra capabilities the stock MAF has, or how much athority the oxygen sensor has to correct the air fuel ratio...

 

[remington115]

awsome thanks

 

[scotts90ranger]

don't take what I say as fact, but going off of the fact that '96 and '01 should use the same basic computer and most sensors, and if you are just using the long block they are the same other than the rotating assembly, having a MAF should account for the extra airflow due to the extra displacement, and if the injectors are larger compared to the 2.3 it should be throwing a bit more fuel in anyway...

the 96 and 01 deff would not use the same computer...totally diferrent engines, one is a OHV 2.3 and the 01 is DOHC 16V 2.3

 

[scotts90ranger]

in early '01 they still used 2.5's, if it's definetely a 2.5 it should work similarly, I'm not saying they have the same ECM's exactly, I mean they should use the same connectors... like I was able to plug the '86 ECM into my '89 wiring harness, sure there aren't as many pins on the '86 but it had the same connector

 

[Ranger Sport Honduras]

ooo sorry, i thought you were talking about the old 2.3 vs the new 2.3.... i always forget that some 01 trucks had the 2.5...

 

[remington115]

yeah its 2.5L and the new computer has the same pin holes and pins in the old harness they fix the same
