Default Beta Swap ECM Pinout Guide

To use the Accent harness with the Beta 2 engine and ECM you need to rearrange the pinout order at the ECM plug and a few changes on the engine bay side. I have figured out an easy way to get at these little wires at the ECM plug, no more cutting and soldering (for the most part) wires. Now you can free the wire/pin and reinsert it.



02 1.6L manual on the left, 00 1.5L manual harness on the right. Although very different on the engine bay side with wires taking different routes, all wires land in almost the same place with the same plug minus maf and map.





The AMP style ECM plug that many Hyundai's used.





Slide this cover up on off, its on there tight.





Remove the 2 yellow clips on both sides of the plug, I used a small flat head screwdriver.

This side is the small clip side only effecting the five larger pins, I have not yet figured out how to free those yet.





With the large clip out you can now free the bulk of the wires.





Look close, every other pin is numbered, to free the wire simply press the tab down, seen there on the right hand side of the plug, and pull the wire out.



Now you will need to re order the pins to mimic your ECM requirements. I have a few pin outs listed below to help, I will expand on this further at a later date.



Now for the Engine bay side, I am going to quote info from jsharptooth91 and his guide. He swapped in a beta 2 (02 Elantra) and used his 1.6L harness (and ECM but that irrelevant) and this is what needed to be done on the engine bay side.



Beta wiring.



When you go to make your connections, make sure they are good connections. I solder them on and have shrink wrap over the connections. This makes for a good connection.



Itís not a whole bunch of wiring changes. We will be using the 1.6L DOHC ecu. It has the same sensors as the beta 2, except the crank sensor we already replaced. The ecu pin out is the same on the 1.5 as the 1.6 except the 1.5 has a MAF and the 1.6 has a MAP.

Here is a diagram of the two sensors.



If you look at the MAP sensor you will see it has numbers on the outer casing 1-4.

If you look at the MAF sensor you will see it also has numbers 1-5. You have to look down inside where it connects to the connector.

Now just match up the corresponding number to the diagram above, itís that simple.

The connections below I had to relocate, either making the cables longer or shorter. When you go to plug them in or try to you will know if you will need to extend the cable or shorten it up.

ē TPS sensor.

ē Coolant temp. sensor.

ē IAC

ē Wire for the oil pressure sender.

ē O2 sensors. I did both. Depending on where your O2 bungs are located.



I think that its, Iím going off of memory, so if I forget something Iím sorry.



I used the Beta coil pack. They have different connectors than the Alpha. I donít have color match ups, but it will work this way. Do one at a time. On the connector you have a big wire and small wire. They are the same on the Alpha (big & small). Cut of the connector leaving your self some extra wire to do the soldering. Now connect the harness big wire to the big wire on the (Beta) connector and the small wire to the small wire. Thatís it! Make sure you do them one at a time, so you donít get the firing order messed up.



Here are some abbreviations for the pinout breakdowns below

acs = accelerator sensor

ccv = canister close valve

cel = check engine light

cmp = camshaft position sensor

cps = crankshaft position sensor

cpv = canister purge valve

dlc = data link connector

dmtl= diagnosis module for tank leakage

ect = engine coolant temp sensor & sender

ftp = fuel tank pressure sensor

isa = idle speed actuator

kns = knock sensor

maf = mass air flow sensor

map = manifold absolute pressure sensor

tcm = transmission control module

tps = throttle position sensor

LC/LC2 00-05 Accent 1.5L/1.6L Manual/Automatic

I compared the ECM wiring schematics from 3 different years, 2000-2002-2005 and 1.5L/1.6L together and for the most part every pin at the ECM is the same with LC2 using an extra wire at the #11 pin, . There is a differance in some of the wire colors on the LC2, the pinout below is the wire size and color code for 2000-02 LC Accents.

RD Tiburons (1997-2001)

or

X3 Accents (1997-1999)



(warning... wire colors may not be the same, the colors shown below are from a 2001 Tib)

I think the EVAP and the Speed Sensors my vary from X3 and RD.

A word of caution: on pins with little barbs that you push in to remove the pin from the connector, push gently and only as hard as required to free the pin. The little barbs can break.

I didnt think about that Stocker, good input. It requires very little force to get the tab down enough to pull the wire out, and the wire should come out easy.
