ECU /relay box wiring diagram

[lemmy01]

Hi,
i have buyed a Atom2 (k20a2+rotrex) last year.
Because of a cheap/bad fuel filter the engine is damaged (low compression on 1. cylinder).

I have a spare k20a2 from a civic with PRA ecu and PRA engine loom.

So i decided to pull out the engine and the hydra nemesis ecu and convert to not charged for now.
Next year i will upgrade the ecu to hondata v4 pro and a fresh engine back to the rotrex setup.

To go back to honda ecu i need some wiring info for the E-Plug on the PRA-ECU,the 101? plug from the engine loom, and the Ariel fuse/relais box. Could  somebody help out?

Google Honda Database 2.0.7
There is a phone app with most of the data you require I believe. I have it on my phone but there is too much data - you are best having a look yourself  - hope it helps.

Thanks, i tried the app but ther is no info about the PRA ecu and nothing about the plug of the engine loom

See tech section - ecu pin outs

Doesn't say what ecu but does have some pin out data.
What car/year is a PRA ecu from?
Might be able to drag some wiring diagrams off my Honda.net

civic ep3 (european).The pinout in tech section of the app are from different ecu's. PRA ist odbII i think.

ep3 2003 - is this of any help?

directly off official hondacom MARIS. 

doesn't show pinout numbers - but by wire colours may be able to trace them.  groups of wires for injectors etc are usually grouped so you should be able to suss out a good bunch of them
hope this helps
