okay guys im having trouble and i used search and found some info but i dont' get what they are saying...ok im doing a h22a1 swap in a 97 coupe ex.....i extend the o2, change from obd2 to obd1 injectors clips,and extended my alternator wire...here is my trouble, the motor came with a external coil..i dont' want to buy a new jdm one so how do you use the one i got now...this is what i did to mine according to the search, from the coil there is three wires...yellow, black/yellow, and blue,,,i hook the yellow(coil) to the black/yellow on the distributor, then i hook the blue(coil) wire to the green on the distributor, now there is one left the black/yellow one(coil)..they say to hook that to a power source, my question is, where is the power source? is that negative or postive? please help, i need this swap done.. and doing this do i need a resistor or something? oh yea can i use a 91 civic map sensor for this swap? or does it have to be a accord or prelude..

here you go. All you have to do is match up wire colors. When it tells you to go to a power source you just need to go to any yellow wire with a black stripe.


ok-----------------------------------------------------------------------
some have asked about how to wire an obd 2 ext coil dizzy to use with a obd1 p13 in an EK
so here ya go. ----------------
for a 99 civic ex, putting in a h22a4 w/ the factory disitributor (obd2 ext. coil), using a obd2-->1 conversion harness and obd1 p13, USE the civic engine harness and modify it to fit the H22.

**((HELMS manuals highly reccomended for this))**

the 99 civic's are obd2.2 or 2b(whichever you call it), the plugs that plug into the ecu have to be rewired to obd2 or (2a) in order to use the conversion harness. (im assuming you know how to do this)

99 civic ex distributor wires (labels & colors):
TDC (top dead center) - ORN/BLU(dizzy color) or GRN(egnine harness color)
TDCM (ground) - WHT/BLU(dizzy color) or RED(egnine harness color)
CKP (crankshaft position) - LT BLUE or BLUE/GRN(dizzy colors) or BLU(engine harness color)
CKPM (ground) - LT BLUE/YEL or WHT(dizzy colors) or WHT(engine harness color)
CYP (cylinder position) - ORN(dizzy color) or YEL(engine harness color)
CYPM (ground) - WHT or BLK(dizzy colors) or BLK(engine harness color)

ICM (ignition control module) - YEL/GRN

Power wire - BLK/YEL
Tachometer - BLU

2000 prelude distributor, ext coil, and CKP/TDC sensor wires (labels & colors)
here is also the ecu locations for obd2 for each of these wires.

4 wires go to CKP/TDC sensor ontop of the crankshaft:
C3 - TDC - GRN
C13 - TDCM - RED
C2 - CKP - BLU
C12 - CKPM - WHT

distributor:
C4 - CYP - YEL
C14 - CYPM - BLK
A20 - ICM - YEL/GRN
tachometer - BLU(should be on 2 prong plug)

EXTERNAL IGNITION COIL will have 3 wires coming out of it. 2 connect to the distributor and 1 goes to a power source.:
GRN@coil, GRN@dizzy - connects coil to dizzy
YEL@coil, BLK/YEL@dizzy- connects coil to dizzy (should be a LARGE wire)
BLK/YEL - connects coil to power source.

yea that is where i look too just wasn't sure where what the power source ..thanks a lot..

hey..i looked at my wires again..you said hook the power sources to any yellow wire with black strip...do you mean black wire with yellow strip...cause the wire that they say to hook up to a power sources is black with yellow strip. when i was going to hook that up to the the yellow with black strip ..i notices that it is black with yellow stripe should i egnore the color or ?????
