Description

Rywire B-series Tucked OBD1 Conversion Engine Harness - 88-00 Civic / 94-01 IntegraThe Rywire OBD1 B series Tucked Engine Harness is nearly identical to the Rywire Mil spec engine harness line with the primary differences being the type of wire used the single white wire color and expandable loom used. All connectors and materials are new. Each connector is crimped with pneumatic heads to ensure an OEM crimp every time, then tagged with a white identification label for easy installation. All heavy interference circuits are protected

The Rywire OBD1 B-series Tucked Engine Harness is nearly identical to the Rywire Mil-spec engine harness line with the primary differences being the type of wire used - the single white wire color and expandable loom used.

All connectors and materials are new. Each connector is crimped with pneumatic heads to ensure an OEM crimp every time, then tagged with a white identification label for easy installation. All heavy interference circuits are protected and grounded with proper wire covering. Rywire engine harnesses are 100% quality tested pin to pin and resistance checked to ensure no voltage fluctuations.

This engine harnesses is made with 92-95 OBD1 ECU connectors and is a plug-n-play affair for 88-91 civic/crx, 92-95 civic, 92-97 delsol, 96-00 civic, and 94-01 Integra vehicles that are utilizing an OBD1 ECU and OBD1 B-series engine.

Optionally, an OBD2 B-series version is available for 96-98 civic, 99-00 civic, 96-99 & 00-01 integra's. That means, this harness retains an OBD1 ecu nature but has OBD2 injector and 10-pin distributor connectors (sorry does not have CKF or secondary 02 sensor plugs). This is targeted for folks who have an OBD2 B-series engine swap but want a clean OBD1 integration. Select the "OBD2x" version of the mentioned vehicle(s) in the pull down menu for this specific harness application.

Certain OBD1--> OBD2 conversions are supported on this harness via OBD1-OBD2A/B ECU jumper harness adapter:

  • Converting to JDM OBD2A/B ecu is supported
  • Converting to USDM OBD2A/B ecu is NOT supported
  • AEM EMS w/OBD2 connectors is supported

Each harness will come with a custom back side sub-harness that will be proprietary to the chassis you choose on the drop down menu. This way if you ever change chassis you will only need a new sub-harness, not a whole new tuck engine harness!

The OBD1 B-series Engine Tuck Harness has the following sensor connectors:

  • Oil pressure sending unit
  • Knock sensor
  • Intake air temp (intake manifold style plug)
  • Engine coolant temp
  • H20 sending unit (for gauge cluster temp gauge)
  • Fan switch
  • 02 sensor (primary 4-wire)
  • Alternator
  • 2 extra wires
  • Injectors x 4
  • MAP
  • TPS
  • VSS
  • IACV (idle air control valve)
  • VTEC solenoid
  • Starter signal
  • Distributor (10-pin 'big plug')
  • Power distribution cap
  • Reverse lights
  • ECU A,B,D plugs

Select your vehicle chassis in the pull down menu when ordering for proper interior sub-harness application.

Select the (OBD2) vehicle option if you would like to have OBD2 injector and distributor connectors for OBD2 B-series engine use (whilst using an OBD1 ecu).

**This listing does NOT come with the Charge Harness

These harnesses are warrantied and guaranteed to work, however they are non-refundable. Because the back-side (interior/shock tower connection) separates from the main harness, the engine harness can be used on multiple chassis's provided the engine itself uses the same components. We sell the back-side harness separately only over the phone for previous engine harness customers.

Indestructible
Color: Green, Pattern Name: Multi Color
Ordered these on a sale..I thought there were 4 bones, but only 2...I have 2 American bullies and 2 Micro bullies..All heavy chewers..These work perfectly for them and they love them...I actually had to order another pack full price so that there was 1 for each dog. Happy with my purchase, happier with the sale price but all 4 like them and can't destroy them so it's a good purchase.

My Pup Said No Thank You
Color: Green, Pattern Name: Multi Color, Color: Green, Pattern Name: Multi Color
⭐☆☆☆☆ My dog usually loves toys like this, so I was excited about them—especially since the colors were fun and it came as a pack of two. Unfortunately, my dog didn’t like these at all and kept choosing her older chew toys instead. They just didn’t hold her interest, which was disappointing. Overall, not worth the money for us.

Update after a week of having this toy
Color: Green, Pattern Name: Multi Color
I thought these were going to be more like a hard rubber but they are a very hard plastic. Keeps my dog busy but best to be supervised while chewing on it. I don’t let her have it when I’m not around so she doesn’t damage her teeth. *UPDATE* The dogs are absolutely obsessed with these toys. I was worried at first it was going to hurt their teeth and gums but they don’t. These have been a great addition to their millions of toys lol. Very happy with my purchase

Very sturdy chew toy
Color: Bacon
My Frenchy loves it! He’s not a large dog, but big for a French Bulldog. (32 lbs). He chews both ends, but prefers the snout. The eyes are cute, but began to peel off within the first week. I easily removed what was peeling. Half of the paint remained intact. When necessary, I will definitely replace it with the same toy.

Great chew toy, long lasting
Color: Bacon
This chew toy has been amazing. We have had it for 2 months with 2 dogs chewy on it and it is still going strong. We have a large Golden who chews on everything and and German Shepherd. Big dogs who chew aggressively. Very impressed! Would definitely buy again!
