    I am looking for a copy of the '89 VFR 750 wiring diagram as supplied by Honda to Australia
    This (unlike what is sugested in some publications) is not the same as '86-'87 model
    I own both and there are considerable differences, including different colors on the wiring and additional safety features on the later bike.
    I am getting a little "older" and find reading "a4" copies impossible, even with glasses, so upsized my small schematic on "a0" paper with wonderful effect - I can read the bloody thing!
    So, with no schematic for the later machineI decided to go down the same path, but cannot find a print for this particular model
    Any help appeciated :)

    Thanks, rc24dk. That is great - where can I buy an original copy now?
    I took a look at the schematic, and it looks the part, but I can't read it
    And as soon as I enlarge the picture it just becomes a pixelated blur
    I can see on other pages of this document that it has all the goods missing on the earlier schematic
    If I can purchase an original, Im sure I shall be able to get it enlarged to "a0" as previously explained
    And the addendum would form an important part of the "copy" of the original manual I have
    Now at least I know where this information was published so thanks for that :)

    Anyone out there with a Second Addendum to the original VFR 750F workshop manual they are prepared to sell me?
    Alternately, a high-resolution copy of the wiring diargam on the last page

    There’s a colour coded wiring diagram for the FJ, FK in the Haynes manual

    I know it’s correct because I used it last year when looking for a fault

    Hi Thumbs- appreciate the suggestion but that advertisement shows a cover picture of the shop manual that clearly says it is for '86 -87 model, despite the accompanied text saying otherwise?
    I already have a "copy" of a genuine Honda shop manual, and it unfortunately does not have the later model wiring diagram, however it is available in the publication of a"second Addendum" as reported elsewhere in this thread.

    I also own a Clymer manual which generously says it covers models '86 -'97 and has a wiring diagram for 1988 (non-US) model. However, I have found errors in this manual, as no doubt have others.
    This diagram I printed off last night and trimmed the item to a4 size (originally covered 2 pages in the manual) and re-connected the overlapping lines
    Tomorrow, when I can get a larger print, I shall enlarge to at least a2 and begin the laborious task of "generally" checking against my bike
    Should it prove to be a reliable replication of what I own, I shall proclaim "mission accomplished"
    Only issue here is the Clymer diagram uses nothing like the layout of the genuine Honda diagrams but seems at first inspection to be accurate in detail and has all the additional accesories found on the later bike
    I shall need to enlist the help of my wife who is well accustomed to my lack of color correctness and can identify the colors on the wires for me!
    Here's hoping

    Well, the Clymer '88 non-US diagram is not the same as the wiring on my '89 model (Dec '88 manufactured) for Australian delivery
    I got it enlarged to a2 this morning and started checking with my wife, some good early results and then............
    They have 13 wires connected to the Spark unit - 2 x 6 wire couplings plus an extra going back to the Taco, and some of these wires have different color codes
    I note the diagram in the "here in published" Addendum 2 has what appears correct for my bike (2 x 6 wires and no additional taco wire) but I cannot read the color codes due to the low resolution of the print - it just pixelates when one tries to enlarge it. That diagram is drawing number 0030Z-ML7-9200
    I tried searching the internet for a copy of Addendum 2, found one in the UK but when pressed for information I found the wiring diagram is a different number, maybe still correct, maybe not?
    If I go out and purchase a Haynes shop manual it may also be incorrect, though it worked for Thumbs in the UK?
    My auto electrical friend tells me this is not uncommon, that manufacturers offen change wiring colors from one year to the next for no apparent reason?

    And so - if anyone can provide me with a high- resolution scan of the 0030Z-ML7-9200 drawing it would be very much appreciated before I tip more coin into my quest to obtain a "correct" wiring diagram. Alternately provide the color codes for the 12 wires connected to the spark unit
    That at least would confirm if the 9200 drawing is what I seek

    No point in searching in Clymer manual as it is US Centric.
    For 88 & 89 US got effectively the 87 model, usually with a 700 engine.

    The rest of the world got a major upgrade : bigger forks, better brakes, improved 4-2-1-2 exhaust, alloy pillion footrest brackets, vastly improved 4 part front fairing.

    This is sometimes referred to as the RC24-2.0030-ML7-9200 is the correct wiring diagram for the Europe market bike. This differs from diagram in Haynes Manual.

    Two 6 pin connectors.

    R/Y No4 Injector & Fuel Cut relay
    Y/W No3
    R/Bu No2
    Bu/Bl No1
    Bl/W Stop Sw & Injector 1
    G Earth

    W/Bu Pulse Generator
    Y/G Tacho
    W/Y Pulse Generator
    Y Pulse Gen
    Lg/R Neutral SW / Clutch Diode / Neutral light
    G/W Clutch Switch

    Hope this helps.

    VFR 750F Addendum Section 25 covers the Rest of World 88. & 89 models. Should be a copy on site I uploaded it years ago.

    The US did not get any "88" or "89" F Models. Nothing. There is no US VFR700F2 (or 750F) with a 1988 or 1989 Model Year Tag. There were of course some leftover 1987 VFR700F2 units on showroom floors that continued to sell over the next couple years. And 1987 US models were all 700, not "usually".

    Actually, the Clymer manual that I own (specifically claims VFR700F & VFR750F. 1986-1989) and does include for "Non US" models in their wiring diagrams.
    To be precise, they cover 1986, 1987, 1988 but not 1989.
    Thank you 50th VFR - the wiring codes for the 2 x 6 pin sockets on my bike appears exactly as per your description above.
    Sorry I did not respond earlier but have been away on holiday, only getting home in time to clear things up before this cyclone hit Brisbane!
    Now basically waiting for it to pass, have found time to catch up on reading - and found your message!
    The two bikes were on the patio but due to the storm, are currently in the family room of the house (where else - they are family?)
    I note you say this is not the same as shown in the Haynes manual - how strange?

    As of today I can confirm the drawing (as indicated by 50thVFR) and others is the correct wiring diagam for my Australian delivered '89 model 750.
    Been a long story for me but 50thVFR sent me a "good" copy of that which was on the forum pages, I had it re-produced in A1 format so I could follow hte lines.
    Then with my wife's help today we check a significant number of different items off the drawing - and they all matched my bike, no exceptions
    So, what we received here in Australia is the same wiring as per the European production (I can't speak for other technical issues)

    A big thanks to all for their help, especially 50thVFR, he deserves special praise for going the extra mile to help
    Regards Skipper
