ok here it is............ PLEASE READ ALL B4 MAKING A POST

Car-1990 civic dx

Motor- 1993 Integra B18a

Problem- wiring is all fucked up.

i have both stock harnesses( civic dx and integra ls). i already swapped the ecu out and that plugged in perfectly. now, i was told i need a resistor box. my car does not have a resistor box. do i need one? next, which harness do i use. i know there has to be some kinds of modification done but which one do i modify? then what exactly do i modify to the harness? i know that my car is dual point fuel injection and that the integra motor is muli port. so i know that there is at least 2 more wires i have to add to something. what do i do? i know that there are people who can do this for a fee but i want to do this my self. that way i have the knowledge of it for future reference and save a bit of money. so please dont post a responce telling me to take it to neal, kenji, jose, or colin. i want to attempt this myself.

now another question. i know reguardless of what motor i put in there, i have a wiring on my hands. would it be a difference if it was a ls motor or a crx SI motor going in there? both motors are muli port. both dont have vtec. would the wiring be the same for the 2 motors?


PLEASE RESPOND WITH AN ANSWER FOR MY HELP. IF YOU HAVE INSTRUCTIONS I CAN FOLLOW (I.E. COLOR CODED WIRE DIRECTION) I'D APPRECIATE IT. THANKS FOR YOUR TIME AND HELP.

 

Okay if the ecu plugged into your harness then it is a 90-91 ls ecu, if it was a 93 it would be obd1 and it would not have plugged in. Now about the resistor box you need to find out if the injectors are peak and hold or saturated.
Peak and hold means you need a resistor box, saturated you don't. To find out take a mutimeter and get a resistance reading across the terminals. If it is between two to three ohms then you have peak and hold injectors and need a resistor box. If the rsistance is much higher, 9 to 10 ohms I believe, then you have saturated injectors and you don't need a resistor box.
AS for thye distributor what are the colors of the plugs? If they are white then that is a 90-91 distributor and it is what you need. If the plugs are grey then it is obd1 and you can't use it.
Use the stock dx harness.

 

i have resistor box 15bucks PErfect shape email me mustardpie55@hotmail.com

 

And not to sure if i would listen to him,Because all honda/integra injectors 86-91 are 6-7Ohm YOu need a resistor box no matter what in all preOdb cars and for integra 0db1 started in the 92 integras and if you want to make it a easy swap BUY A 90-91 si HARNESS OR cut the 4injector wires off the integra harness and splice them into the ecu plugs..........

 

Uh... KJ knows what hes talking about... listen to him.

 

This post is over four months old, I'm sure he got it worked out and doesn't need to buy your resistor box. And all the info I gave is correct, If you are going to say I'm wrong and try to correct me then at least list good info. Peak and hold injectors are between 2 and 3 ohms, You don't need a resistor box in obd0 cars if you do the wiring right and run saturated injectors. Where do you get your info from , like telling someone to run a block guard and an msd box on an NA honda. That would be the biggest waste of money and time. Before giving somone advice on something that could either cost them time or money at least try to make sure it is right.

rant over.
