Default dpi to MPFI swap... quick ?

OK... I done a lot of searching on the topic, but I can't figure out who is right...

According to my CHiltons manual (I know its crap) the factory Wiring diagram for my Std. shows Injector 1 @ A1 and A2 and Injector 2 @ A3 and A4... Now they wires are just y'd at some point so really the connections are the same. The manual shows the same thing I saw at the harness. Not for the SI or MPFI it shows that injectors 1-4 are in pins A1-A4 in order as seems logical. Now for all the conversion diagrams I see, they show pins A3 and A7 to be switched for injectors 2 & 4 but that's totally wrong according to the manual. My local honda buddy also said the same as my assumption, pins A1-A4...

So in other words I'm confused and a bit nervous to try this out. On one hand Chiltons cuts corners and I don't totally trust them... but so far it's been right. Secondly The pins labeled B10 and B12 are labeled for the AC system according to Chiltons, so they don't seem right either...

HELP

Where do I make the changes for the Crank Angle Position Sensor???

Jung

Thanks

the difference here is the way the pins are numbered - the factory diagrams number the pins on the top row as A1 thru A9, B1 thru B10, etc. and the bottom row as A10 thru A18, B11 thru B20, etc. - most of the diagrams that you see on the forums and different web sites number the pins with top row as odd numbers and the bottom row as even numbers - you are correct, on the factory diagram B10 & B12 are for electric load detector and A/C, however on all of the other diagrams, these would be called B19 & B4 - so, B10 & B12 on the other diagrams would be B15 & B16 on the factory - don't know how this got started, but if you look at the swap wiring info on http://www.zcspeed.com you will see it numbered same as the factory diagrams.
