Default h22a7 DC2 wiring problems (using LS Harness)

ok here goes. I've got an h22a7 which you all know is the JDM accord type r motor. It's from a 2000 Accord Type R. Now what I have is a 94 integra LS. I need help with wiring. I've already taken out the vtec wiring and am merging it with my LS harness already, however, there is the problem of EGR (which i'm probably not even going to hook up) and then there is the knock sensor (but i'm going to use the wiring from the LS knock sensor and just snip and solder), but what i don't know is the MAP Sensor is located on the IM instead of on the firewall and it's got 3 wires (h22a7) while my ls harness only has two. Another big concern is the distributor. My LS had 9 wires, whilst my h22a7 only has 4. Probably because it is OBD II. I am going to be using a P13 for now until i save up some more money to get a chipped ECU, maybe a p75 or p28 with spoon or mugen chip. The LS harness that i'm using is only the Engine bay harness and it will be plugging into the plug at the firwall opening.

I DON'T NEED TO HEAR ANY FLAMES OR ANY GRIPES ABOUT WEIGHT AND HANDLING. CHANCES ARE IF YOU'RE AGAINST THE SWAP, YOU HAVEN'T DONE IT, THEREFORE YOU WOULDN'T KNOW. IF YOU ARE THE FEW WHO HAVE DONE THE SWAP FEEL FREE TO GIVE ME ADVICE.

HERE'S MY SETUP.

H22A7 2000 ACCORD TYPE R MOTOR
1994 Acura Integra LS
DC Sports Header 4-2-1 ( i don't know if i'm going to keep this )
AEM Cam Gears
V AFC II black
Progress Suspension Coilovers CS1
Progress Suspension Rear Sway Bar
P13 ECU
LS Harness (modified)
ACT Heavy Duty Clutch Kit
ACT Xact Streetlite Flywheel
Hasport Motor Mounts

Soon to get Hasport stage 2 Axles
SI Rims on low profiles
Brembo upgraded rotors

Im assuming your going to use the LS engine harness modified to fit the H22a engine and P13 OBD1 ecu, in that case this is probably what id do:

<TABLE WIDTH="90%" CELLSPACING=0 CELLPADDING=0 ALIGN=CENTER><TR><TD>Quote &raquo;</TD></TR><TR><TD CLASS="quote">the problem of EGR (which i'm probably not even going to hook up) [/i]</TD></TR></TABLE>

If your going to hook it up, then you need the plug and wires and run them back to the ecu:

EGR Valve Lift Sensor
D12 - White/Black
D19 - Red/White
D21 - Green/White

EGR Solenoid
A11 - Red
12v - Black/Yellow

The EGR solenoid which is mounted near the timing belt cover on the accords/ludes, refer to the helms for the vacuum diagrams otherwise send me pm ill give you them

<TABLE WIDTH="90%" CELLSPACING=0 CELLPADDING=0 ALIGN=CENTER><TR><TD>Quote &raquo;</TD></TR><TR><TD CLASS="quote">what i don't know is the MAP Sensor is located on the IM instead of on the firewall and it's got 3 wires (h22a7) while my ls harness only has two.[/i]</TD></TR></TABLE>

I havent came across a 2 wire MAP sensor before, 3 wires are needed for OBD1, in that case refer to an OBD1 wiring diagram and work out the missing one you need to add...

MAP Sensor

D17 - White/Blue
D21 - Blue/White
D19 - Red/White

<TABLE WIDTH="90%" CELLSPACING=0 CELLPADDING=0 ALIGN=CENTER><TR><TD>Quote &raquo;</TD></TR><TR><TD CLASS="quote">Another big concern is the distributor. My LS had 9 wires, whilst my h22a7 only has 4.

Use a OBD1 H-series Dizzy, from memory it should plug straight into the LS loom
If your going to use a P13 ECU, you will most likely will need to get the OBD1 fuel injectors and hook up the resistor box as well...

Otherwise save your money and get a chipped P28 or P72

ok. that 3 wire sensor.. is actually the IACV.. what do i need to wire that **** up? i'm thinking about converting to the LS IACV sensor instead.. umm yah.. as far as wiring goes.. i'm going to try and get my hands on an OBDI distributor too.. i think that i'm going to keep the saturated fuel rail.. i'm sure it'll do fine on the p13 ecu..
