d15 swap help

[maxhumper]

Im trying to help a friend of mine get his swap to run better and finish the wiring project. just a few questions here..

this is a jdm d15 that includes the jdm d15 computer but the wiring job isn't so clean.. the map sensor isn't hooked up and has no wires leading to it, even the plug for the sensor isn't there. off what motors can i use the map sensor off to use on the d15?

can i use a wire harness off another model honda to make things clean with no worries of bad wiring?

can anyone give me a wiring diagram of how the wiring of this swap might go? its a 91 civic si that the d15 is in.


thanks for your help

Which d15b is it? What OBD generation? Vtec? what wire harnesses do you have available?

always use the engine harness that came in the car and make the necessary wiring changes to it - the 91 Si has the MAP on the firewall and the connector for it is not on the engine harness - it just comes thru the firewall - if this is an OBD1 D15B VTEC, the MAP is on top of the throttle body and you need to extend the wires on the MAP connector and plug it into the MAP on the throttle body - as festivagt said, need more information on what the engine is

d15b1 ob1 jdm vtec unsure of the wire harness's i have the harness that came out of the original motor that was in it. its a 91 civic si and the harness that is in there right now and has many connections already made which look right so far, besides a few loose ended wires that i will have to find out what they need to be connected to, car is getting a new fuel pump because the old one just went...
